Question

What’s the mass of Ca(NO3)2 need to make 981.46 g of solution if we want 64.46% solution.

Answer 1

Hey there!

We need to find 64.46% of 981.46g.

Divide 64.46 by 100 then multiply that by 981.46.

64.46 ÷ 100 = .6446

.6446 x 981.46 = 632.6

You need 632.6 grams of Ca(NO₃)₂.

Hope this helps!
