What is the molar mass of 81.50g of gas exerting a pressure of 1.75atm on the walls of a 4.92l container at 307k?

Molar mass of gas is 238.6 g/mol

Explanation:

Using ideal gas equation:  

PV = nRT

P= pressure = 1.75 atm

V= volume = 4.92 L

n = no of moles =

R= gas constant =0.0821 Latm\molK

T = temperature = 307 K

R= gas constant = 8.314 J/Kmol

T= temperature = 190.7 K

M= molecular mass of gas = ?g/mol

the positions which points up in upward carbon and down in downward carbon are axial

and vice versa holds true for equatorial positions

so the correct answer with labelled diagram will be
