Molecular weight of Cu(OH)2 =64+(16+1)*2=98
According to stoichiometry,
40 gram of NaOH is used to precipitate 98 g of Cu(OH)2
Hence comma space 200 space gram space of space NaOH space will space be space used space to space precipitate equals space 98 over 40 cross times 200 equals 490 space gm space of space Cu left parenthesis OH right parenthesis subscript 2
