Could someone please provide me the steps as how to solve this? I have the answer, and if you get it correct, I will rate you 5 stars.

In the gravimetric determination of Zn^2+, 2.2024 g sample was dissolved and made up to volume in a 100.0 mL flask. A 10.0 mL aliquot were precipitated by adding a soluble pyrophosphate salt and heating the precipitate to a solid Zn2P2O7 (304.728 g/mol). The final, dried product weighed 0.1314 g. What is the percent weight of Zn (65.39 g/mol) in the original sample?
