QUESTION:
A sample of gas has a mass of 38.8 mg. Its volume is 224 mL at a temperature of \(55^{\circ} \mathrm{C}\) and a pressure of 886 torr. Find the molar mass of the gas.
ANSWER:Step 1 of 3
Ideal gas equation:
A mathematical relationship established between variable quantities that is pressure, temperature, number of moles and volume for a true gas is known as an Ideal Gas Equation. It is given by the formula:
PV = nRT
Where;
P = Pressure
V = Volume
n = Number of moles
R = Gas constant
T = Temperature
