A series of measurements are made to determine the molar mass of an unknown gas. 1st, a large flask is evacuated and found to have a mass of 134.567g. 2nd, it is filled with the gas to a pressure of 735 torr at 31C(31 degrees celcius, i cant put the degree sign) and remassed. Its mass is now 137.456g. Finally, the same flask is filled with water at 31C and found to weigh 1067.9g. (The density of water at this temperature is 0.997g/mL)
Assume the idel gas equation applies, and calculate the molar mass of the gas.
PV=nRT (manipulate the ideal gas law to include mass annd molar mass in relation to n). R= .08206 L atm/K mol
the answer i got was 25.72g/mol...is that right? if it is say yes, if it isnt say no, and tell me the right answer
