Answer 1

Hope it helps, cheers!!!

Answer 2

Answer: The molecular mass of the gas is 33.6 grams.

Explanation:

We are given:

Density of gas = 1.5 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:

$Density=\frac{Mass}{Volume}$

Putting values in above equation, we get:

$1.5g/L=\frac{\text{Mass of gas}}{22.4L}\\\\\text{Mass of gas}=33.6g$

Hence, the molecular mass of the gas is 33.6 grams.
