A drop of water of 1.8 gm weight has 60,230,000,000,000,000,000,000 molecules. Express it in standard form.

Answer 1

A drop of water of 1.8 gm weight has 60, 230, 000, 000, 000, 000, 000, 000 molecules = 6.023 × 10²² .

• A standard form number is represented as a product from 0 - 9 multiplied by the ten's power . So here as it is of the order 10²², the answer is 6.023 × 10²³ .
