Asked by Tesla
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.

Use the ideal gas law solved for n:
n = PV / (R T)
Calculate: P = 750 torr, V = 1.35 L, R = 62.396 L·torr/(mol·K), T = 17.0°C = 290.15 K.
n = (750 torr)(1.35 L) / (62.396 L·torr·mol⁻¹·K⁻¹ × 290.15 K)
≈ 1012.5 / 18104.2
≈ 0.0559 mol
So n = PV/RT and n ≈ 0.0559 mol.
n = PV / (R T)
Calculate: P = 750 torr, V = 1.35 L, R = 62.396 L·torr/(mol·K), T = 17.0°C = 290.15 K.
n = (750 torr)(1.35 L) / (62.396 L·torr·mol⁻¹·K⁻¹ × 290.15 K)
≈ 1012.5 / 18104.2
≈ 0.0559 mol
So n = PV/RT and n ≈ 0.0559 mol.
