Professor Organic Chemistry Tutor, thank you for another awesome explanation of How to Calculate Gas Density given the Molar Mass at STP in AP/General Chemistry. The relationship between Pressure and Density, Temperature and Density and Molar Mass and Density is a great way to grasp the concepts of Gas Density and Molar Mass Problems in Modern Chemistry. This is an error free video/lecture on YouTube TV with the Organic Chemistry Tutor.

This video came out just as we're going to start gases tommorow haha

shouldn't I need to found the same result using the P/T ratio? first I have tried to find the P/T ratio from d = P.M/R.T and then I have used this equation d2 = P/T * M/R to find asked density. But my result wasn't the same as yours.
