Asample of gas weighs 10.1 g and occupies a volume of 5.65 l at 60 °c and 580 torr. identify the gas sample.

The question is incomplete, here is the complete question:

A sample of gas weighs 10.1 g and occupies a volume of 5.65 L at 60 °C and 580 torr. Identify the gas sample.

(a) (molar mass = 119.4 g/mol)  

(b) (molar mass = 44.02 g/mol)

(c) (molar mass = 64.07 g/mol)

(d) (molar mass = 17.03 g/mol)

(e) (molar mass = 70.90 g/mol)

The gas sample is having molar mass of 64 g/mol

Explanation:

To calculate the molar mass of the gas, we use the equation given by ideal gas equation:

PV = nRT

Or,

where,

P = Pressure of the gas = 580 torr

V = Volume of the gas = 5.65 L

w = Weight of the gas = 10.1 g

M = Molar mass of gas = ?

R = Gas constant =

T = Temperature of the gas =

Putting values in above equation, we get:

Hence, the gas sample is having molar mass of 64 g/mol

do u have any choices to choose from ? ?

your answer would be a. 12.5 kg
