The molar mass of this gas is 59.0 g/mol.
Molar mass is described as the mass in grams of 1 mole of a substance. The gadgets of molar mass are grams in keeping with mole, abbreviated as g/mol. The mass of an unmarried isotope of any given detail (the isotopic atomic mass) is a cost concerning the mass of that isotope to the mass of the isotope carbon-12.
Calculation:-
PV = nRT
P = 742 torr = 0.976 atm
P × molar mass = density × R × T
0.976 * molar mass = 2.34* 0.0821*300
0.976 * molar mass = 57.6
molar mass = 59.0 g/mol
Therefore, the molar mass = 59.0 g/mol
