Question

Calculate the number of moles, the number of molecules and the volume in cm3 of 0.32g of: 1)CH4 2)SO2 gases at STP
​

Answer 1

Explanation:

no. of moles of CH4= given weight/molecular weight

=0.32/16

=0.02 moles

no. of moles of SO2=given weight/molecular weight

=0.32/64

=0.005 moles

no. of molecules of CH4=moles*NA

=0.02*6.022*10²³

=0.12044*10²³

=1.2044*10²²

no. of molecules of SO2=moles*NA

=0.005*6.022*10²³

=0.030110*10²³

=3.0110*10²¹

volume at stp of CH4=moles*22.4

=0.02*22.4

=0.448dm³

=448cm³

volume at stp of SO2=moles*22.4

=0.005*22.4

=0.1120dm³

=112cm3
