### 9.13 6th Edition

For this question, the answer states to just assume 1 mol of the gas to calculate the equation. Will this always be the case if the equation does not explicitly state how many moles we are working with? And will such equations be on the midterm?

I think this will be the case if they do not give you enough info in order to solve for moles with PV=nRT
