Question

from dimensional analysis,derive the unit of 'M' in the equation PV=WRT/M

Answer 1

Explanation:

M is the molar mass of gas which is in grams per mole of the gas. The ideal gas equation is PV = nRT which is the gas equation relating pressure(P) volume(V), to n(the number of moles of gas), R(the universal gas constant), and T(temperature of the gas).
