Question

Ajay had samples of gases in two closed jars labelled as A and B. Jar A
contained 8 g. of Methane (CH4) and Jar B contained 11 g. Of Carbon dioxide
(CO2 ) . Calculate and find out which jar /sample has more number of
molecules?

Answer 1

molar mass of methane is 16g but in jar there is 8g of methane = 8/16 = 1/2

molar mass of carbon dioxide is 44g but in jar there is 11 g of carbon dioxide = 11/44 = 1/4

As 1/2 > 1/4 molecules of methane are more as compared with mass of carbon dioxide
