Answer :

The mass of water is, 26.845 g

The volume of water is, 26.92 mL

The volume of flask is, 26.92 mL

Explanation : Given,

Mass of flask stopper = 32.634 g

Mass of water and flask stopper = 59.479 g

Density of water = 0.9973 g/mL

First we have to calculate the mass of water.

Mass of water = Mass of water and flask stopper - Mass of flask stopper

Mass of water = 59.479 g - 32.634 g

Mass of water = 26.845 g

Thus, the mass of water is, 26.845 g

Now we have to calculate the volume of water.

$\text{Volume of water}=\frac{\text{Mass of water}}{\text{Density of water}}$

$\text{Volume of water}=\frac{26.845g}{0.9973g/mL}$

$\text{Volume of water}=26.92mL$

Thus, the volume of water is, 26.92 mL

Now we have to calculate the volume of flask.

Volume of flask = Volume of water = 26.92 mL
