Methane undergoes slow atmospheric oxidation and produces carbonmonoxide. If 2xx10^(22) oxygen molecules are used in such oxidation, what weight of methane is consumed?

Methane undergoes slow atmospheric oxidation and produces carbonmonoxi

1.	Methane undergoes slow atmospheric oxidation and produces carbonmonoxide. If 2xx10^(22) oxygen molecules are used in such oxidation, what weight of methane is consumed?
Answer» Solution :Slow atmospheric oxidation of methane is given by the equation `2CH_(4)+3O_(2) to 2CO+4H_(2)O` 3 moles of `O_(2)="2 moles of "CH_(4)` `3 xx 6.022 xx 10^(23) O_(2)` molecules = The weight of `CH_(4)` consumed `(2 xx 16)"GRAMS of "CH_(4)` `2 xx 10^(22) O_(2)` molecules=? The weight of `CH_(4)` consumed `=(2 xx 10^(22) xx 32)/(3 xx 6.022 xx 10^(23))=0.354 G`
