Explanation / Answer

At equilibrium:
SrCO3     <---->     Sr2+     +          CO32-  

                     s                  s       

Ksp = [Sr2+][CO32-]
5.6*10^-10=(s)*(s)
5.6*10^-10= 1(s)^2
s = 2.366*10^-5 M

Molar mass of SrCO3,
MM = 1*MM(Sr) + 1*MM(C) + 3*MM(O)
= 1*87.62 + 1*12.01 + 3*16.0
= 147.63 g/mol


Molar mass of SrCO3= 147.63 g/mol
s = 2.366*10^-5 mol/L
To covert it to g/L, multiply it by molar mass
s = 2.366*10^-5 mol/L * 147.63 g/mol
s = 3.494*10^-3 g/L
Answer: 3.49*10^-3 g/L
