Question

How many water molecules are in a block of ice containing 1.25 mol of water (H2O)

Answer 1

Molecules = 7.5 × 10²³ molecules

Step-by-step explanation:

Given:

Moles = 1.25 mol

Avogadro's No. =
`N_(A)` = 6.022 * 10²³

Required:

Molecules = ?

Formula:

Molecules = Moles ×
`N_(A)`

Solution:

Molecules = 1.25 × 6.022 × 10²³

Molecules = 7.5 × 10²³ molecules
