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?

Respuesta :

Answer:

mass of calcium chloride = 290.49g

mass of water = 494.61 g

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 = [tex]37.0 percentage X 785.1[/tex]

= [tex]\frac{37X785.1}{100}=290.49g[/tex]

The mass of water = 785.1-290.49 = 494.61 grams
