An aqueous solution is 15.0% by mass of copper(ii) sulfate pentahydrate, cuso4∙5h2o. what
is the molarity of cuso4 in this solution at 20°c? the density of this solution at 20°c is1.167
g/ml(molecular weight of cuso4∙5h2o = 249.5, molecular weight of cuso4 = 159.5)

0.702 mol / dm³.

Consider a 1,000 mL sample of this solution. Mass of the sample:

.

The mass ratio of copper(II) sulfate pentahydrate in this sample is 15 %. In other words, among that 1,167 grams of the solution is .

Number of moles of in that of the hydrate:

.

Concentration of the hydrate:

.

because of all the things that happen around the us, many people get into arguments which sadly could get physical, but we should actually make a change for that.
