The ksp value of radium sulfate RaSO_{4} is 4.2\times 10^{-11}. If 25 mg of radium sulfate is placed in1.00x102mL of water, does all of it dissolve? if not howmuch dissolves?

This is the solubility of radium sulfate
Now we have to calculate the molarity of the givenamount of RaSO4
Moles of solute = mass(g) / molarmass(g/mol)
molarity(M) = moles of solute/V(L)
We know 1000mg = 1g and 1000ml = 1L
So find this value and compare with s(where s is themolar solubility) , if it is less than s then it does notdissolve, if its more than the value s then it dissolves to aextent and if equal the value then all dissolves.
