Question

Briefly describe two methods one might use to find the molar mass of a newly synthesized gas for which a molecular formula was not known

Answer 1

1. Molar mass (M) = mRT/PV

2. Molar mass (M) = dRT/P

Step-by-step explanation:

For the newly synthesized gas, we can determine the molar mass using the two methods described below.

1. We can use the temperature, pressure, volume and mass of the gas to calculate the molar mass. Mathematically,

M = mRT/PV

where:

M is the molar mass, m is the mass, R is the universal gas constant,T is the absolute temperature, P is pressure and V is volume.

2. We can also use the density of the gas at a certain pressure and temperature conditions to estimate its molar mass. Mathematically,

M = dRT/P

where:

M is the molar mass, d is the density, T is the temperature, and P is the pressure.
