Problem 69P

An experiment shows that a 248-mL gas sample has a mass of 0.433 g at a pressure of 745 mm Hg and a temperature of 28 °C. What is the molar mass of the gas?

Step by Step Solution

Step 1 of 3

According to the ideal gas equation is as follows.

.......................(1)

Rearrange the equation (1) as follows.

.....................(2)

n= Number of moles of the gas

P = Pressure of the gas

V = Volume of the gas

R = Gas constant

T = Temperature of the gas.
