how many grams of copper (II) Chloride are formed in the double replascement reaction of 1.1 g copper (II) oxide and excess hydrochloric acid?

1 answer

CuO + 2HCl ==> CuCl2 + H2O

Convert 1.1 g CuO to moles. moles = grams/molar mass.

Using the coefficients in the balanced equation, convert moles CuO to moles CuCl2.

Now convert moles CuCl2 to grams. g = moles x molar mass.
