If you wanted to make 350mL of a 20% solution of CuSO4, how many grams of CuSO4 would you need?

-
Total = 350 mL
CuSO4 = 20 %
So,
20% of 350
=20/100 * 350
=70g (CuSO4)

( 350=CuSO4 + water
350= 70 + water
Water = 350 - 70
Water = 280 g )

Hope You got it!!

-
20 w/w %= 0.2 x 350= 70 g CuSO4 + 280 g H2O
