Question

Ordinary water contains one part of heavy water per 6000 parts by weight. The number of heavy water molecules present in a drop of water of volume 0.01ml is (density of water is 1g/ml

Answer 1

Answer:

The number of heavy water molecules present in drop of water of volume 0.01 ml is (Density of water is 1gm/ml). 1 gram of heavy water in 6000 gram of ordinary water. If 6000g of ordinary water contains 1g of heavy water. Now, 1 mole of heavy water contains 6.022 × 10^23 molecules of heavy water.
