Question

A student measures the mass of a clean, dry flask and stopper is measured using a laboratory balance. The mass of the empty stoppered flask is 36.724 g. The flask is then filled with deionized water and the mass of the filled stoppered flask is determined to be 65.858 g. The mass of the filled stoppered flask equals the sum of the mass of the empty stoppered flask plus the mass of the water. what is the volume of the flask?

Answer 1

Answer:

Volume of flask = 29.134 cm³

Explanation:

Mass of water = mass of filled stoppered flask - mass of empty stoppered flask.

Mass of water = 65.858 - 36.724 = 29.134 g

Density of water = 1 g/cm³

Volume = mass/ density

Volumeof water = 29.134 g/ 1g/cm³ = 29.134cm³

Therefore, volume of flask = 29.134 cm³

Answer 2

Answer:

The volume of the flask is 103.6 g

Explanation:

We know that density is equals to mass per unit volume. So for finding the volume, we have to put the values of masses of water and flask and density of water in the formula.

First the masses of both water and flask is added which is 102.6 g and the density of water is 0.997 g/cm3. So by puting these values in the formula of volume i. e. volume = mass/ density, so we get 103.6 cm3 volume.
