Calculate
1oogm
of c&o atoms in
of CaCo3​

Answer 1

Explanation:

0 g sample of calcium carbonate, C a C O 3 (molar mass = 1 0 0 g/mol) 1 Answer. of CaCO3 = 40 + 12 + 3 X 16=100g 100 g of CaCO contains = 3 x 6.022 x 10^23 atoms of oxygen There fore, 50 g CaCO3 will contain = 3 X 6.022 X 10^23 X 50/100 = 9.033 X 10^23 atoms of oxygen The molecular weight of CaCO3 is equal to 100…
