Question

how many water molecules are present in 2 ml of water (d = 1 g/ml)?

please anyone with proper answer!​

Answer 1

Explanation:

mass of one mL of water = volume × density

= 1 mL × 1 g/mL = 1 g

Number of moles = 1 / 18

Number of molecules = 1/ 18 × 6.023 × 10^23

= 3.346 x 10^22 molecules
