Question

what mass of sodium suphate will react with 5.22 g of barium chloride to produce 6.10 g of sodium chlorride and 2.80 g ofbarium sulphate

Answer 1

6.10 +2.80=8.9

according to law of conservation of mass5.22 + x=8.9
and x=8.9-5.22=3.68 answer

Answer 2

let the mass of sodium chloride be 'x'

x+barium chloride =Barium sulphate + sodium chloride

X + 5.22 gram = 2.8 + 6.10 gram

X + 5.22 gram = 8.9 gram

x =8.9 gram - 5.22 gram

x =3.68 gram
