Answer:

[tex]\boxed{\text{6.95 u; Li}}[/tex]

Explanation:

1. Atomic mass of T

To get the atomic mass of T, you calculate the weighted average of the atomic masses of the isotopes.

That is, you multiply the atomic mass of each isotope by a number representing its relative importance (e.g.., its percent of the total).

[tex]\begin{array}{ccrcr}\textbf{Atom} & \textbf{Mass/u} &\textbf{Percent} & \textbf{Calculation}& \textbf{Result/u}\\^{6}\text{T}& 6.02 & 7.42 & 6.02 \times 0.0742 & 0.45\\^{7}\text{T}& 7.02 & 92.58 & 7.02 \times 0.9258& 6.50\\& & &\text{TOTAL } = &\textbf{6.95}\\\end{array}[/tex]

2. Identity of T

Lithium has an atomic mass of 6.64 u.

Element T is lithium.

Number of liters (L) = 2430 L, 243 decaliters (daL) is equal to 2430 liters (L).

To convert 243 decaliters (daL) to liters (L), you need to use the conversion factor: 1 decaliter (daL) is equal to 10 liters (L).

So, to convert from daL to L, you can use the following equation:

Number of liters (L) = Number of decaliters (daL) × Conversion factor

Number of liters (L) = 243 daL × 10 L/daL

Number of liters (L) = 2430 L

Therefore, 243 decaliters (daL) is equal to 2430 liters (L).

Answer:

28.57 grams are in (NO3)2

Explanation:

Answer:

The bonds that exist between their atoms and molecules differ on an atomic scale.

Explanation:

The three basic states of matter are solid, liquid, and gas. The major difference between them is the strength of the bonds that hold their molecules together. This affects the way that the molecules interact with each other.

The intermolecular forces binding solids together are very strong. This makes solids rigid and not able to move about freely, but rather, only able to vibrate about a mean position.

The intermolecular forces binding liquid atoms together are a lot weaker than that of solids. This makes liquids able to flow.

The intermolecular forces binding gas molecules together are the weakest. As a result, the gases can move about freely and occupy no definite volume.

Answer:

202,020 pennies

Explanation:

The amount of pennies in 1 dollar is 100.

Basically, you just multiply the whole dollar amount (2020) by 100 and then add 20 to find the amount of pennies.

(2020)(100)+20= 202,000+20= 202,020 pennies.

Answer:

202,040 pennies

Explanation:

$1 is equal to 100 so just multiply 100 by 2,020 and then you can add the extra 20 cents

Answer:

1425 mmHg.

Explanation:

The following data were obtained from the question:

Initial volume (V1) = 1.5 L

Initial pressure (P1) = 1 atm

Final volume (V2) = 0.8 L

Final pressure (P2) =?

Next, we shall determine the final pressure of the gas by using the Boyle's law equation as follow:

P1V1 = P2V2

1 × 1.5 = P2 × 0.8

1.5 = P2 × 0.8

Divide both side by 0.8

P2 = 1.5/0.8

P2 = 1.875 atm

Finally, we shall convert 1.875 atm to mmHg.

This can be obtained as follow:

1 atm = 760 mmHg

Therefore,

1.875 atm = 1.875 × 760 = 1425 mmHg.

Therefore, the new pressure of the gas is 1425 mmHg.
