reaction vessel at 37.5 C exerts a pressure of 771 mmHg? ( The compound is in the gas phase)

This problem can be formulated as below using the relation PV=nRT, we can obtain the molar mass as belowP=771 mmHg, T=37.5C=310.5K, V=103mL=1 L, R=62.36L mmHg K−1 mol−1n=PV/RT=771x1/(310.5x62.36)=0.0398 molTherefore the molar mass=517x10^-3/0.0398=13.0 g/mol Best regards.

using the relation PV=nRT, we can obtain the molar mass as below

P=771 mmHg, T=37.5C=310.5K, V=103mL=1 L, R=62.36L mmHg K−1 mol−1

n=PV/RT=771x1/(310.5x62.36)=0.0398 mol

Therefore the molar mass=517x10^-3/0.0398=13.0 g/mol
