I need 0.200 mol each of zinc metal and copper (ll) nitrate for an experiment. What is the mass of copper (ll) nitrate ?

Answer 1

(0.200 mol Cu(NO3)2) x (187.5558 g Cu(NO3)2/mol) = 37.5 g Cu(NO3)2

Answer 2

Erica ---  find the molar mass of Copper(II) nitrate  then multiply by 0.200

 == Find the atomic mass of zinc  then multiply by 0.200

This is the easy part of chemistry.
