Question

The density of gas at STP is 1.2 gram per litres its molecular weight is nearly​

Answer 1

Answer : The mass of gas is 26.88g

Explanation :

We are given:

Density of gas = 1.2 g/L

At STP conditions:

1 mole of gas occupies 22.4 L of volume

And 1 mole of a substance is known as the molecular mass of that substance.

To calculate the mass of gas, we use the equation:

Density = Mass / Volume

Putting values in above equation, we get:

1.2g/L = Mass of gas / 22.4L

=> Mass of gas = 22.4 x 1.2

= 26.88g

Hence, the molecular mass of the gas is 26.88 grams.
