|
Answer» `"1 G of "CO_(2)` `"No. of moles of 1 g of "CO_(2)=(1)/(44)` `"No. of molecules"=(1)/(44)xx6.023xx10^(23)` `=1.368xx10^(22)" molecules of "CO_(2)` (b) 1 g of `N_(2)` `"No. of molecules "=(1)/(28)xx6.023xx10^(23)` `=2.151xx10^(22)" molecules of "N_(2)` (C ) 1 gof `H_(2)` `"No. of molecules "=(6.023xx10^(23)xx1)/(2)` `=3.011xx10^(23)" molecules of "H_(2)` (d) 1 g of `CH_(4)` `"No. of molecules "=(6.023xx10^(23)xx1)/(16)` `=3.764xx10^(22)" molecules of "CH_(4)` So (c ) is the correct answer. |
