Cu(OH)2 => CuO + H2O
1 mole 1 mole
moles of Cu(OH)2 = mass Cu(OH)2 * (1/Molecular Weight Cu(OH)2)
moles of Cu(OH)2 = 1.4 g Cu(OH)2 * (1 mol / 97.54 g Cu(OH)2) = 0.01435 mol
moles of Cu(OH)2 = moles of CuO
grams of CuO = moles CuO * MW CuO
grams of CuO = 0.01435 mol * 79.54 g / 1 mol = 1.1416 g

How’s that set up in dimensional analysis?

Using appropriate significant figures your answer would be 1.1 g assuming the math is correct.03/20/20
