How to find molar weight using the combined aka general gas law?

This is a question I gotta do for my chem lab today and I have no idea how one would use this formula to calculate a molar mass since you can't calculate moles using this law and the weight isn't supplied to us. Please help

Answer:

You cannot determine molar mass of a gasby using the combined gas equation: P1V1/T1 = P2V2/T2 This can...

Daltons law with the combined gas law - over water?

Hi! I'm doing a review assignment and forgot how to do this. Please don't just give me the answer, please walk me through the steps. Thanks! 1632.0 cm^3 of hydrogen gas is collected over water at a pressure of 162.4 kPa and 70.0 degrees C. What is the...

Answer:

162.4 kPa minus 31.2 kPa = 131.2 kPa (that's the pressure of the dry gas when at 70 C) P1V1 / T1 = P...
