Determine the number of moles of air present in 1.35 L at 750 torr and 17.0°C.

Ideal Gas Law formula: PV = nRT(R = 62.396 L•torr/mol•K)

Which equation should you use?

P equals StartFraction n R T over V EndFraction.

n equals StartFraction R T over P V EndFraction.
n equals StartFraction P V over R T EndFraction.
