Calculate the density of methane gas, CH4, in kilograms per cubic meter at 25 degrees C and 956 mmHg.
I got .8252 g/L but am getting confused with the converting units.

Is it just .8252 kg/cm^3? because multiply 1000cm^3 / 1000kg

Yes it is but I don't know how you arrived at the 0.8252. We may have used slightly different numbers.
P*Molar mass = d*RT
(956/760) x 16/(0.08206*298) and I get 0.8230 which is 0.823 to there s.f.
You may have used a slightly different molar mass than 16.
