Question

If the mass of 3.011x10 ^ 22 molecules of a gaseous compound in STP is 3.2 g, the gram of molecular weight of the compound
To diagnose. What is the volume of 3.2 g gaseous compound in STP?

Answer 1

Explanation:

since the no of molecules is given first calculate the mole

3.011×10^22÷6.022×10^23

=5×10^-2 moles

mass of these molecules =3.2g

molecular mass=given mass×moles

=3.2×5×10^-2

=16×10^-2g

moles=volume/22.7

volume=5×10^-2×22.7

=113.5×10^-2 liters
