Question

calculate the gram molecular mass of the following compounds
copper sulphate
potassium Bicarbonate​

Answer 1

M(Cu) 63.54 ≈ 64

$M( CuSO_{4} ) :$

• 1(Cu) + 1(S) + 4(O)
• 1(64) + 1(32) + 4(16)
• 64 + 32 + 64
• 128 + 32
• 160 g/mol. or amu

$M(KHCO_ 3) :$

• 1(K) + 1(H) + 1(C) + 3(O)
• 1(19) + 1(1) + 1(12) + 3(16)
• 19 + 1 + 12 + 48
• 20 + 60
• 80 g/mol. or amu
