Question

1. Calculate the mass of 1.8 moles of water molecule.​

Answer 1

Explanation:

Mass of 1 mole of water = 18g

Therefore, mass of 1.8 moles of H2O = 18×1.8 g

= 32.4 g

Answer 2

Answer:

1 molecule of H2O contains 10 electrons.

So one mole that is equal to 22.4 L of H2O will contain 6.022 × 10^23 × 10 electrons. So 1.8 ml will have - 6.022×10^23×1.8×10/22.4 ×1000=6.022×10^21×1.8/22.4.
