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
