Chemistry: During one researcher s experiment, the total mass of the gas-generating solid and entire assembly was 52.1487g before the reaction and 52.1098g after the reaction. if the number of moles of gas generated was calculated to be 8.854 x 10-4 mol, what is the molar mass of the gas?

43.93 g/mol

Explanation:

The mass of the gas before reaction = 52.1487 g

The mass of the gas after reaction = 52.1098 g

Mass of gas generated = 0.0389 g

Moles of the gas = $8.854\times 10^{-4}\ moles$

The formula for the calculation of moles is shown below:

$moles = \frac{Mass\ taken}{Molar\ mass}$

Thus,

$Molar\ mass = \frac{Mass\ taken}{Moles}$

$Molar\ mass= \frac{0.0389\ g}{8.854\times 10^{-4}\ moles}$

Molar mass of the gas = 43.93 g/mol
