4. when cu(oh), is heated, it decomposes to black cuo and h,o. consider, how
many grams of cuo will be formed from the decomposition of 6.59 g of cu(oh)?
if only 5.17 g of cuo are produced instead, what is the percent yield?

The percent yield of CuO is 96%. The percentage yield shows the extent to which reactants are converted to products.

What is percent yield?

The percent yield is the actual yield divided by the theroretical yield multiplied by 100.

Now we have the equation;

2Cu(OH)2 → 2CuO + 2H2O

Number of moles of Cu(OH)2 = 6.59 g/98 g/mol = 0.067 moles

Since 2 mole of Cu(OH)2 yeilds 2 moles of CuO

0.067 moles alos yields 0.067 moles of CuO

Mass of CuO = 80 g/mol * 0.067 moles of CuO = 5.36 g

Hence, percent yield =  5.17 g/5.36 g * 100 = 96%
