Question

8.2 litre of an ideal gas weight 9.0 gram at 300 Kelvin and 1 ATM pressure . The molecular mass of gas is ​

Answer 1

Answer:

: The molecular mass of gas is 27 g/mol.

To calculate the number of moles, we use the equation given by ideal gas equation:

Or,

where,

P = pressure of the gas = 1 atm

V = Volume of gas = 8.2 L

m = mass of gas = 9.0 g

M = molecular mass of gas = ?

R = Gas constant =

T = temperature of the gas = 300 K

Putting values in above equation, we get:

Hence, the molecular mass of gas will be 27 g/mol.
