The density of a gas is found to be 1.56 ~g / L at 745 mm pressure and 65^ C . What is the moleculer mass of the gas?

Options

  1. A44.2 u
  2. B4.42 u
  3. C2.24 u
  4. D22.4 u

Correct answer

A. 44.2 u

Step-by-step solution

Given, p=745 ~mm = 745 760 atm aligned & T=65^ C =65+273=338 ~K & aligned M & = d R T p = 1.56 0.0821 338 745 / 760 & =44.2 u aligned aligned
