A 0.094 g of CuSO4*5H20is dissolved and diluted to the mark in a 500.0-mL volumetric flask. A 2.00-mL sample of this solution is transferred to a second 500.0-mL volumetric flask and diluted.
What is the molarity of CuSO4 in the final solution?
To prepare the solution directly, what mass of CuSO4*H2O would need to weighed out?

well, you have 2/500 * .094g copperIIsulfate pentahydrate in the second flask up to a volume of 500mL

molarity= molessolute/volumeinliters

answered already, 2/500*.094g
