What is the molar mass of a gas with a density of 4.03 g/L at –73EC and 1,140 torr?

44.1 g/mol

Explanation:

Step 1: Convert the temperature to the Kelvin scale.

We will use the following expression.

K = °C + 273.15

K = -73°C + 273.15

K = 200 K

Step 2: Convert the pressure to atm

We will use the relationship 1 atm = 760 torr.

Step 3: Calculate the molar mass of the gas

We will use the following equation derived from the ideal gas equation.
