Determine the molar mass of an unknown gas, if that unknown gas effuses via an orifice at a rate 5.42 x 10^-9 mol/s, and methane (CH4) effuses through the same orifice at the rate of 1.30 x 10^-8 mol/s, both gases having the same temperature and pressure.
An unknown gas effuses 0.250 times the rate of He. What is the molar mass of the unknown gas? Your answer should have three significant figures.
4- av pusi Identify the unknown diatomic gas that effuses as fast as CO(g) under the same temperature and pressure conditions.
Methane gas, CH4, effuses through a barrier at a rate of 0.568 mL/minute. If an unknown gas effuses through the same barrier at a rate of 0.343 mL/minute, what is the molar mass of the gas? **Please explain question **this question has already been posted but the answer was not very explicative. Thank you!
