pure substances have a molarity of 1.
but, if you need a calculation, you could start with the definition of molarity (M) is grams of solute/molar mass of solute x liters of solution, there is some missing information for this problem to be solved as a solution but with a conversion factor, you should be able to find an answer.
Moles (n) can be calculated as follows:
68.7 g Pb (n/207.1g) = .332 mol Pb
117 g Sn (n/118.7g) = .989 mol Sn
density: d = m/v = g/mL
lead 11.34 g·cm−3
tin 7.31 g/ml
these conversions can be put into the analysis equation and should be able to solve.
