Question

What is the volume of 1 mole of water (density of water = 1gm/ml) .

Answer 1

• To find the volume of 1 mole of water, you first need the mass of 1 mole of water. That can be calculated as = 2(Hydrogen) + 16(Oxygen)= 18g water.
• Density = $\frac{Mass}{Volume}$ = 1g/ml
• Rearranging the equation to fond the volume -
• $$\begin{gathered} Volume=\frac{Mass}{Density} \\ Volume=\frac{18g}{1g/ml}=18ml \end{gathered}$$
• Therefore, a volume of 1 mol of water =18ml
