Question

Какую массу соли необходимо взять для приготовления 450 грамм хлорида меди и 15% раствора

Answer 1

M(соли)=450*0.15=67.5г

Answer 2

Calculating the Mass of Salt Needed

To calculate the mass of salt needed for preparing 450 grams of copper chloride and a 15% solution, we can use the following formula:

m(salt) = (mass of solution) * (percent concentration)

Substituting the given values: m(salt) = 450g * 15%

Calculating the mass of salt needed: m(salt) = 450g * 0.15

The mass of salt needed is 67.5 grams.
