Question
Which of the following contains maximum number of molecules?
Options
1g CO2
1g N2
1g H2
1g CH4
Solution
1g H2
ag of CO2 = `1/44 xx 6.022 xx 10^23` molecules
= 1.368 x 1022 molecules
1g of N2 = `1/28 xx 6.022 xx 10^23` molecules
= 2.15 × 1022 molecules
1g of H2 = `1/2 xx 6.022 xx 10^23` molecules
= 3.011 × 1023 molecules
1 g of CH4 = `1/16 xx 6.022 xx 10^23` molecules
= 3.76 × 1022 molecules
