You need to know the molecular mass of the Cu(OH)2. Look in the periodic table the atomic mass for each of the elements in the formula and add them. 1Cu + 2xO + 2 x H = 63.54 + 2 x 16 + 2 x 1 = 97.56
Or you can google "Cu(OH)2" an in Wikipedia you will find the molar mass 

Now you know that one mole of Cu(OH)2 = 97.56 g

34 g of Cu(OH)2 x 1 mole Cu(OH)2 / 97.56 g Cu(OH)2 = ?????  mole of Cu(OH)2
