How many water molecules are there in 36 g of water? express your answer as a multiple of avogadro's number na. (the molecular structure of a water molecule is h2o.)'?

Respuesta :

M H2O = 18 g/mol

In 18 g of water we have 6,02 × 10^23 molecules.

18 g ----- 6,02 × 10^23
36 g ----- x

x = 36 g × 6,02 × 10^23 / 18 g = 12,04 × 10^23 = 1,204 × 10^24

Answer is 1,204 × 10^24

:-) ;-)

Water molecules present in the 36 gm of water in the terms of Na are 1.204 × 10²⁴.

What is Avogadro's number?

Avogadro's number gives the relation of the constituent particles of the molecules with that of the whole sample.

We know,

Mass of water = 18 g/mol

If 18 g of water contains 6.02 × 10²³ molecules then 36 gm will have,

36 ×  6.02 × 10²³ / 18 = 1.204 × 10²⁴

Therefore, 1.204 × 10²⁴ molecules are present in 36 gms of water.
