The density of an elemental gas is 1.7824 g/l at stp. what is the molar mass of the element. what is the element?

The molar mass of the element is 40 g/mol and element is Calcium.

Explanation:

At STP:

1 mole of a gas contains 22.4 L of volume

Molar mass is defined as the mass of 1 mole of a substance.

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

Volume of gas = 22.4 L

Density of gas = 1.7824 g/L

Putting values in above equation, we get:

The element having molar mass 40 g is Calcium.

Hence, the molar mass of the element is 40 g/mol and element is Calcium.
