Question

2.9 gram of a gas at 95 degree Celsius at the same volume as a 0.184 gram of hydrogen at 17 degree Celsius at the same pressure what is the molar mass of the gas ​

Answer 1

Explanation:

PV=NRT

PV=WRT/MV

SAME PRESSURE AND SAME VOLUME

WRT/MV= CONSTANT

SO PUT THE VALUE IN FORMULA

2.9×368/M=0.184×290/2

M=2.9×368×2/290×0.184

M=40 gram/mole
