Question

how many molecules of water are there in 36g water ​

Answer 1

Answer:

gm molecule of water = 18 g of water. It is equal to Avogadro's number (NA), namely 6.022 x1023. If we have one mole of water, then we know that it will have a mass of 2 grams (for 2 moles of H atoms) + 16 grams (for one mole O atom) = 18 grams.

Answer 2

Answer:

1.2 * 10 to the power of 24

Explanation:

1. Convert mass of water to mole of water using the molar mass of water as a conversion factor.

2. Convert moles of water to molecules of water using Avogadro's number as a conversion factor.
