Melissa you should probably just ask Mr Earls because apparently anyone doing the question has no idea what to do
ksp = [Ca][C2O4]
2.3*10^(-9) = x^
4.8*10^-5 = x
now sub that in as C in n = cv
then convert that answer to mass (m = n*Mm)
and that's the final answer
1.105*10^-3 g
that's the final answer
