1. The problem statement, all variables and given/known data At 0 degrees, and 1 atm, 0.6 mol of a gas occupies a volume of 0.0134 m^3. what is the mass density? The number density is 2.69x10^25 m-3, the average distance between the gas molecule is 4nm and the total mass is 17.685g. 2. Relevant equations n=N/Na 1u=1.66x10^-27 mol-1 3. The attempt at a solution I tried to find N so I did 0.6/6,022x10^23 and got 9.96x10^-25. Then I multiplied this by 2.69x 10^-25 and go 2.68x10^-49 which was wrong. I'm not exactly sure how to solve the problem, so any help is appreciated!
