Question

sodium chloride is 39.34% sodium. what mass of sodium chloride will contain 2.00 g of cholrine

Answer 1

Solution:
If sodium chloride is 39.34% sodium, then chlorine in sodium chloride:
100 – 39.34 = 60.66%
If in 60.66% - 2 g
in 100% - x,
Then x=100x2/60.66=3.297 g
3.297 g of sodium chloride will contain 2.00 g of chlorine.
