Question
The volume occupied by ten molecules of water (density 1g cm-3 ) is: 1. 18 cm3 2. 22400 cm3 3. 6.023 ×× 10-23 cm3 4. 3.0 ×× 10-22 cm3
Solution
To find the volume occupied by ten molecules of water, we need to use the density of water, which is given as 1g cm-3.
Step 1: Determine the molar mass of water. The molar mass of water (H2O) is calculated by adding the atomic masses of hydrogen (H) and oxygen (O). The atomic mass of hydrogen is approximately 1g/mol, and the atomic mass of oxygen is approximately 16
