How are 0.50 mol Na_(2)CO_(3) and 0.50 M Na_(2)CO_(3) different? |
|
Answer» Solution :Molar MASS of `Na_2CO_3 = (2 XX 23) + 12 + (3 xx 16) = 106` 0.50 mol `Na_2CO_3` means `0.50 xx 10^6 = 53` g of `Na_2CO_3`. It refers to the mass only.`0.50 M Na_2CO_3` means 0.50 mol, i.e., 53 g of `Na_2CO_3` are present in 1 litre of the solution. Thus, it refers to the strength of the solution. |
