Question

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

Open in App

Solution

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 = $\frac{M a s s}{V o l u m e}$ = 1g/ml
Rearranging the equation to fond the volume -
$V o l u m e = \frac{M a s s}{D e n s i t y} V o l u m e = \frac{18 g}{1 g / m l} = 18 m l$
Therefore, a volume of 1 mol of water =18ml
