Sagot :

Answer:

41.8 g of water.

Explanation:

To solve this, we introduce the concept of mol.

1 mol of anything contains 6.02×10²³ particles.

In this case, we talk about molecules of water.

Molecular weigh is 18 g/mol which indicates that 1 mol of water weighs 18 g.

So let's do the conversion

(18 g of water / 6.02×10²³ 1 mol of molecules) . 1.4×10²⁴ molecules = 41.8 g
