Question

A solution of CaCl2 in water forms a mixture that is 37.0% calcium chloride by mass. If the total mass of the mixture is 785.1 g, what masses of CaCl2 and water were used?

Answer 1

mass of calcium chloride = 290.49g

mass of water = 494.61 g

Step-by-step explanation:

The percentage of calcium chloride in the mixture is 37.0%

It means in each 100g of mixture the mass of calcium chloride = 37.0 g

if the total mass of the mixture = 785.1 g

the mass of calcium chloride =
`37.0 percentage X 785.1`

=
`(37X785.1)/(100)=290.49g`

The mass of water = 785.1-290.49 = 494.61 grams
