Question

100 grams of which gas contains of the maximum number of Gram molecules 1)SO2 2)O2 3)He 4)H2​

Answer 1

oxygen is the right answer

Answer 2

100 grams of gas that contains the maximum number of Gram molecules is 4)H2.

• Several gram molecules mean several moles.
• So, we have to calculate several moles of the following gases to find the maximum number of gram molecules.
• Number of gram molecules in SO2 =
• $\frac{100}{64} = 1.56 \: moles$Number of gram molecules in O2 =
• $\frac{100}{32} = 3.12moles$
• Number of gram molecules in He =
• $\frac{100}{4} = 25 \: moles$
• Number of gram molecules in H2 =
• $\frac{100}{2} = 50 \: moles$
• Henceforth, 100 grams of gas that contains the maximum number of Gram molecules is H2.
