Answer 1

Answer:

PLEASE MARK IT AS A BRAINLIEST ANSWER

your answer is 83 g/mol

Explanation:

as we know , PV=nRT

where P=pressure,

V= volume,

n=no of moles

R = universal gas constant

T= temperature.

PV=WRT/M. where W = weight of gas and M= molar mass of the gas

so, PV/W=RT/M

thus P/d=RT/M

so M =RTd/P

M= (0.083×400×2.5)/1

M=83

Thus the molar mass of gas is 83 g/mol
