Calculate the total number of oxygen atoms present in 0.5 moles of H_(2)SO_(4) |
|
Answer» Solution :Number of MOLECULES present in 0.5 moles of `H_(2)SO_(4) = 0.5 xx 6.022 xx 10^(23) = 3.0 xx 10^(23)` One molecule of `H_2SO_4` contains 4 atoms of oxygen. Total number of atoms present in `3.0 xx 10^(23)` molecules = `3.0 xx 10^23 xx 4 = 1.2 xx 10^24` HENCE, 0.5 moles of `H_2SO_4` CONTAIN `1.2 xx 10^24` atoms of oxygen. |
