Answer 1

From the equation : M= dRT/P
where, M=molar mass of the gas, d= density of the gas, R= universal gas constant, T= temperature in Kelvin, P= pressure.
Given, d= 5.5 g/L, R= (L bar) /(K mol), T=298 K, P= 2 bar.
So, putting all the values in the equation we get:
M= (5.5 × 0.083 × 298)/2
M=68.0185 g.
