My teacher gave me this question for homework need help A copper sulfate solution contained 0.100 moles of copper sulfate dissolved in 0.500 dm3 of water. Calculate the mass of copper sulfate in 30.0 cm3 of this solution. Relative formula mass (Mr): CuSO4 = 159.5

The answer you are looking for is option d

Seems cool i guess ttyl

Answer is: value of q is 5·10⁻⁶m.chemical reaction: mg²⁺(aq) + co₃²⁻(aq) → mgco₃(s).c(mg²⁺) = 2.5·10⁻³ m; concentration of magnesium cations.c(co₃²⁻) = 2.00·10⁻³ m; concentration of carbonate anions.q = c(mg²⁺)  · c(co₃²⁻).q = 2.5·10⁻³ m  · 2.00·10⁻³ m.q = 5·10⁻⁶m.q = 0.000005 m.
