Question

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.

Answer 1

Answer: PV/RT = n = N equals startfraction P V over R T endfraction Explanation:

Answer 2

1. PV=nRT
2. Dive both sides by RT to isolate the n (moles).
3. Answer: PV/RT = n = N equals startfraction P V over R T endfraction
