Calculate the molar mass of a gas if a.798 grams occupies 1.000L at 1.000atmand 25.00 degrees Celsius

19.46 g/mol

Explanation:

First of all, we have to calculate the number of moles of the gas. We can do it by using the ideal gas equation, which states that:

where we have:

p = 1.00 atm is the pressure of the gas

V = 1.00 L is the volume of the gas

n is the number of moles

is the gas constant

is the Kelvin temperature of the gas

Solving for n,

Now we can calculate the molar mass of the gas, which is given by:

where

m = 0.798 g is the mass of the gas

n = 0.041 mol is the number of moles
