Question

How many molecules are in 41.8 g H2O?

Answer 1

Answer:

7.63 × 10²³ molecules

Explanation:

First, convert grams to moles using the molar mass of water (32.988 g/mol).

41.8 g  ÷  32.988 g/mol  =  1.267 mol

Next, convert moles to molecules using Avogadro's number (6.022 × 10²³).

1.267 mol  ×  6.022 × 10²³ molecules/mol = 7.63 × 10²³ molecules
