can someone explain in detail how molar mass, Avogadro's number, and volume are all connected through moles? Im so confused :(

Answers

Answer:

See Explanation

Explanation:

By definition, 1 mole is the mass of substance (or, formula mass in grams) containing 1 Avogadro's Number (N₀ = 6.02 x 10²³) of particles. That is ...

1 mole of hydrogen atoms (H) = 1.00794 grams

1 mole of molecular hydrogen (H₂) =  2.01588 grams

1 mole of any substance = 1 formula weight in grams

1 mole = 1 Avogadro's Number (N₀) = 1 formula weight in grams

In the concept of 'gas laws' 1 mole of any (all) gas at STP conditions ( => 0°C & 1 atmosphere pressure) occupies 22.4 Liters & is known as the 'molar volume' of a gas at STP. If the temperature &/or pressure change the volume will not be 22.4 Liters.

For reactions whose coefficients are balanced to the lowest whole number values (i.e., no fractional coefficients) the equation is known as the 'standard reaction' and conditions  are assumed to be STP and the coefficients of gas phase components indicate molar volumes. Example ...

Given   N₂(g) + 3H₂(g) => 2NH₃(g)  is assumed to be at 0°C; 1 Atm pressure.

Molecular Nitrogen = 1 molar volume = 22.4 Liters of N₂(g)

Molecular Hydrogen = 3 molar volumes = 3 x  22.4 Liters of H₂(g) = 67.2 Liters of H₂(g)

Molecular Ammonia = 2 molar volumes = 2 x 22.4 Liters of NH₃(g) = 44.8 Liters of NH₃

What do u mean by electronic configuration? What are basic requirements while writing electronic configuration of an element (atom) ?

Answers

Yes that is right I look it up thanks for the points

The basic requirement while writing the electronic configuration of an element (atom) is its atomic number.

Explanation:

The electronic configuration of an element is the distribution of its electrons in different energy levels around the atomic nucleus.It only requires an atomic number of an element to write its electronic configuration.The atomic number is equal to the number of protons in an atom and that is equal to the number of electrons.And the filling of electrons is done according to the Aufbau principle, the electrons will be first filled in the atomic orbitals with lower orbital energy before filling the atomic orbital with higher energy.The sequence of the atomic orbitals from lower energy to higher energy is:

    [tex]1s, 2s, 2p, 3s, 3p, 4s, 3d, 4p, 5s, 4d, 5p, 6s, 4f, 5d, 6p, 7s, 5f, 6d...[/tex]

For example:

  The atomic number of gallium is 31, its electronic configuration will be:

   [tex][Ga]=1s^2 2s^2 2p^63s^2 3p^6 4s^2 3d^{10} 4p^1[/tex]

An ideal gas occupies a volume V at an absolute temperature T. If the volume is halved and the pressure kept constant, what will happen to it's temperature?



a. It will halve to T/2.


b. It will increase to 3T.


c. It will increase to 2T.


d. It will remain the same.

Answers

Answer:

It will be halve of T

Explanation:

V1 = V

T1 = T

V2 = ½V

T2 = x

V1/T1 = V2/T2

V/T = ½V/x

Vx = ½VT

2Vx = VT

2x = T

x = ½T

C.
a variable that is kept constant.
d.
a variable that is used as a control.

Answers

Answer:

a. directly changed by the experimenter.

Explanation:

In the case of mathematical modeling, analytical modeling , and experimental sciences, the number of dependent variables based upon the amount of independent variables.

The dependent variables represent the result or outcome whose changes is being determined.

An independent variable expressed in the name form like experimental or expected variable, is a variable i.e. created in an experiment in order to verify the effect on a dependent variable

Therefore the option a is correct

I need help I don’t get this

Answers

Visit: gotit-pro.com

Explanation:

1) Convert pressure to atm
119 kPa x 1 atm/101 kPa = 1.18 atm

2) Convert temperature to Kelvin
35 + 273 = 308 K

3) Use PV=nRT and solve for V
(1.18 atm)(V)=(0.0972 mol)(0.0821)(308 K)

V = (0.0972 mol)(0.0821)(308 K) / (1.18 atm)

V = 2.08 L
