Question

1
A gas has density 2.41 g/liter at 25 c at 770mm of hg. Find its molecular mass?​

Answer 1

Ideal gas equation with respect to density will be : PM = dRT. In the formula, P is pressure, M is molecular mass, d is density, R is gas constant and T is temperature. Thus, the molecular mass of gas is 58.96 gram/mol.
