Question

A sample of argon has a mass of 5.75g. The sample has a volume of 2.3L at a pressure of 100kPa and a temperature of 28 degrees C. What is the Molar Volume? Answer is 15.84 L/mol but I don't know how to get it

Answer 1

\[\large n=\frac{ v }{ Mv }\]
n=no. of moles
v=volume
M(v)=Molar volume

Answer 2

you can find the number of moles, n
\[\large n=\frac{ m }{ M }\]
n=no. of moles
m=mass
M=Molar mass (in this case for Argon =40
