Answer:
4. 58.5 grams of sodium and 91.5 grams of chloride
Explanation:
The Answer of this question mainly lies in Ch2 Science of class 9 . You know that concentration of a substance can be obtained by the following formula i.e
Amount of Substance/ Total Amount of solution ×100
And as per the Mathematical aspect we can obtain the amount of substance by the formula
Total Amount of solution/100 × percentage of concentration of the Substance.
So as per the Above formula the answer can be obtained as
Nacl=150g
% of Na=39%
so, Mass of Na= 150/100×39= 1.5×39= 58.5g
% of Chlorine=61%
so, Mass of Chlorine= 150/100×61= 1.5 ×61 = 91.5g
Hope this will help you.
