<h3></h3>

From the calculations and the statement of the general gas equation, the volume of the gas becomes 28.8 L

<h3>What are gas laws?</h3>

The gas laws are used to show the relationship between the variables in problems that has to do with gases.

In this case, we have to apply the general gas law as follows;

P1V1/T1 = P2V2/T2

P1V1T2 = P2V2T1

V2 =   * 22L *  1.5 atm * 273K/313K * 1 atm

V2 = 28.8 L

yan [13]

Answer:

Molarity = 0.21 M

Explanation:

Moles <em>solute </em>(mol) = Volume <em>solution</em> (L) x Molarity <em>solution </em>(M)

0.56 mol NaCl = 2.7 L x M

M = 0.2074074074
