How many moles are there when you have 3.5 g SO3?
What is the mass in grams of 0.700 moles of water, H2O?
answer choices
18.02g/mol
18.04g/mol
12.6g/mol
14.00g/mol
The mass in grams of 0.700 moles of water (H₂O) = 12.6g/mol (option C)
The mass of a chemical in a mole is known as its molar mass.
It is the total atomic mass of every element that is present in that molecule. The molar mass unit is g/mol.
Determine the molar mass of the water(H₂O):
Molar masses of 1 g/mol of hydrogen and 16 g/mol of oxygen make up a mole.
The chemical formula for water is H₂O.
The water's molar mass is thus:
H₂O = (2 x 1) + 16
= 18 g/mol
Moles of water = 0.700
The molar water (H₂O) mass = 18 g/mol
Object's mass is determined by:
m = (moles of the sample) x (molar mass of the compound)
So, mass of the water (H₂O):
= (0.700) x (18)
= 12.6 g/mol

A row of chemical elements makes up a period in the periodic table. The number of electron shells is the same for every atom in a row. Periods are the horizontal divisions or rows in the periodic table, and groups are the vertical divisions or columns.
Periods are shown in the table from top to bottom, numbered 1 through 7. Because they have the same number of orbitals, elements with the same period have identical masses but different characteristics. In other words, the electrons on the same outermost level, which is precisely the number that distinguishes each period, are a characteristic of the elements of a certain period. For instance, the third period elements have electrons up to level three.The number of the energy level increases as the periodic table's period numbers do.

The pH scale may be traced back to a collection of standard solutions whose pH has been determined by worldwide agreement.
The potential difference between a hydrogen electrode and a standard electrode, such as the silver chloride electrode, is measured in a concentration cell with transference to derive primary pH standard values.

Which type of soil would likely drain water the fastest?
Sandy soil would likely drain water the fastest.
Soil is composed of minerals, organic matter, water and gas. It is divided into three classes viz. sand, silt and clay.
The ability of a soil to absorb or drain water depends upon the pore size of the soil particles.
In case of clayey soil, the pore size is comparatively large than sandy soil so clayey soil will absorb the water molecules in its pores .On the other hand, the pore size of sandy soil is relatively small, so it cannot retain the water in its pores, hence it can drain water easily.
Due to this reason, sandy soil is usually used in filtration process.

How to find partial pressure from mole fraction and total pressure?
To find partial pressure from mole fraction, we have to multiply mole fraction with total pressure in the event.
How to calculate partial pressure using an example?The formula for partial pressure is expressed as Pfraction = molefraction x Ptotal. Partial pressure is the result of multiplying the mole fraction by the total pressure. Let's look at the example below to make it simpler for you to understand:
Consider a chamber with 2.611 atm of pressure, 24.2 g of He, and 4.32 g of O₂. In this instance, we must first get the mole fraction before calculating the partial pressure.
24.2 g Neon x 1 mol Neon / 20.18 g Neon = 1.199 mol Neon
4.32 g Oxygen x 1 mol Oxygen / 31.998 g O₂ = 0.135 mol Oxygen.
Total moles = 1.199 x 0.135 = 1.334 mol gas
Mole fraction Ne = 1.199 mol/1.334 mol = 0.899
Mole fraction O₂ = Oxygen: 0.135/1.334 = .101
Then find the partial pressure
PNe = mole fraction Ne x Ptot = 0.899 x 2.611 atm = 2.35 atm
PO2 = mole fraction O ₂ x Ptot = 0.101 x 2.611 atm = 0.264 atm

4.0 mol O2 reacts?
[?] mol Al2O3
The number of mole of Al₂O₃ formed when 4.0 moles of O₂ reacts, given the reaction is 2.67 moles
How do I determine the number of mole of Al₂O₃ formed?From the given stoichiometry of the reaction (i.e 6.0 moles of Al reacts with 4.0 moles of O₂ to form Al₂O₃), we can see that O₂ is the limiting reactant.
Knowing that O₂ is the limiting reactant we can easily determine the number of moles of Al₂O₃ formed when 4.0 moles of O₂ reacts as follow:

if a 10.0 g sample of cobalt -60 is left alone how much will be left after 21.2 years the half-life of cobaltt-60 is 5.3 years
If a 10.0 g sample of cobalt -60 is left alone 0.63 g will be left after 21.2 years the half-life of cobaltt-60 is 5.3 years.
What is half life period ?The term half life period is defined as the time required by a radioactive substance to transform into a different substance.
Given :
T = half life of cobalt-60
= 5.3 years
λ = decay constant for cobalt-60 = ?
decay constant is given as follows
λ = 0.693 / T
Substituting the given values
λ = 0.693/5.3
= 0.131
N₀ = initial amount of cobalt-60
= 10 g
t = time of decay
= 21.2 years
N = final amount of cobalt-60 after time "t"
final amount of cobalt-60 after time "t" is given as
N = N₀
Substituting given values
N = 10
N = 10 x 0.0622 g
N = 0.63 g
Thus, if a 10.0 g sample of cobalt -60 is left alone 0.63 g will be left after 21.2 years the half-life of cobaltt-60 is 5.3 years.
