  1. Molar Mass From Density of a Gas Practice Problems Created by: Miss K. Marshall

  2. A gas has a density of 0.902 g/L. What is the molar mass of this gas? Ans: 20.2g/mol • What is the density of oxygen gas at STP? Ans: 1.43g/L • The density of an elemental gas is 1.7824 g/L at STP. What is the molar mass of the element? Ans: 39.9g/mol • The densities of gases A, B, & C at STP are 1.25 g/L, 2.86 g/L, and 0.714 g/L, respectively. Calculate the molar mass of each substance. Identify each substance as ammonia (NH3), sulfur dioxide (SO2), chlorine (Cl2), nitrogen (N2), or methane (CH4). Ans: gas A: 28.0g, Nitrogen; gas B: 64.1g, SO2; gas C: 16.0g, CH4
