Question

What mass if lead trioxinitrate pbno32 would be required to yield 12

Answer 1

Explanation:

Pb(NO3)2 + 2NaCl ==> PbCl2 + 2NaNO3

mols PbCl2 = g/molar mass

Convert mols PbCl2 to mols Pb(NO3)2 using the coefficients in the balanced equation.

Now convert mols Pb(NO3)2 to g. g = mols x molar mass.
