Question

Number of electrons in 1.8 ml of H2O (liquid ) is

a) 6.02 * 1023 b) 3.011 * 1023 c) 0.6022 * 1023 d) 60.22 * 1023

Answer 1

Answer:

1000ml of water = 1000 GM of water

Explanation:

So H2O liquid = 18ml= 2(1g )hydrogen + 16g oxygen =18g

Given = 1.8 ml

No. of electrons = 1.8 ml/ 18ml × (avogadro no.) 6.022×10^23

= 0.1 × 6.022 ×10^23

option c = 0.6022×10^23
