Answer:
45 mol
Explanation:
First you need to balance the equation:
6K + Cr2O3 = 3K2O + 2Cr
the proportion of the coeficients of potassium and chromium oxide is 6 to 1 so we need to multiply 7.5 by 6 to get 45.

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
