How do you calculate the mass of lead (II) nitrate, #Pb(NO_3)_2#, necessary to make 50.0 mL of a 0.100 M solution?
First, we'll look at formula for Molarity.
Molarity = No. of moles of solute / Vol. of solution (in L)
Before putting values, it helps to know that
Now we also know that
Molar mass of
So mass of
