Answer:

Na = 23u , S = 32u , 0 = 16u

Na2SO4 = 2 x 23 + 32 + 16 x 4 = 142 u

% of Na in Na2SO4 =  $\frac{46}{142}\times&space;100$   = 32.99 %

% of S in Na2SO4 =  $\frac{32}{142}&space;\times&space;100&space;=&space;22.54%$

% of 0 in Na2SO4 =  $\frac{64}{100}&space;\times&space;100&space;=&space;45.07&space;%$
