How are 0.50 mol Na2CO3and 0.50 M Na2CO3 different?



Q.25:- How are 0.50 mol Na2CO3and 0.50 M Na2COdifferent?

 

 

Answer:-

Molar mass of Na2CO3 = (2×23)+12.00+(3×16) = 106 g mol-1



∴0.50 mol Na2COmeans 0.50×106g = 53g
0.50 M Na2COmeans 0.50 mol of Na2COi.e. 53g of  Na2COare present in 1litre of the solution.
