First take the Idea Gas Law

PV = nRT (R Is sometimes written Kb)

Turn all units into their respective SI Units

Convert 744 torr to pascal = 744 torr = 99 191.8421 pascals

2.30 L to Cubic Meters = 2.30 litres = 0.0023 cubic metres

R = Gas constant = 8.314472

PV = nRT


n = PV/RT = (99 191.8421 * 0.0023)/(285 * 8.314472) = 0.0963Mol
