Question

how many grams of copper metal will react completely with 4.50 L of 6.00 M HCl?
Cu (s) + 2HCl (l) = CuCl2 + H2 (g)

Answer 1

Answer 2

6.00 M HCl means for every L of HCL, there are 6 moles of HCL

therefore, simply multiply volume * molarity to get the moles of HCl

once you have moles HCl, use the equation to go to moles Cu (2 mol HCl = 1 mol Cu)

then multiply moles Cu by molar mass of Cu to get grams
