Question

If 50g CaCO3 decompose to give 26g CaO & 22g CO2.
Where Ca=40, C=12 & O=16.
1. Calculate mass of impurities in the 50g CaCO3.
2. Calculate the % impurities in 50g CaCO3.
3. Calculate the % yield of CaO from the CaCO3

Answer 1

If 50g CaCO3 decompose to give 26g CaO & 22g CO2.

If 50g CaCO3 decompose to give 26g CaO & 22g CO2. Where Ca=40, C=12 & O=16.

If 50g CaCO3 decompose to give 26g CaO & 22g CO2. Where Ca=40, C=12 & O=16.1. Calculate mass of impurities in the 50g CaCO3.
