# Unlocking the Mystery of Volume Calculation

## How can we determine the volume of an object using mass and density?

In a laboratory experiment, a student measures the mass of a clean, dry flask and stopper. The mass of the empty stoppered flask is 36.724 g, and when filled with deionized water, the mass becomes 65.858 g. How can we calculate the volume of the flask based on this data?

## Answer:

The formula to calculate the volume of an object is volume = mass / density. In this case, we need to find the mass of the water added to the flask, which is the difference between the mass of the filled stoppered flask and the mass of the empty stoppered flask.

By subtracting the mass of the empty stoppered flask from the mass of the filled stoppered flask, we get the mass of the water added to the flask, which is 29.134 g. Given that the density of water is 1 g/cm³, we can then calculate the volume of the water added to the flask by dividing the mass of water by the density.

Volume of water = 29.134 g / 1 g/cm³ = 29.134 cm³

Therefore, the volume of the flask can be calculated as 29.134 cm³ based on the data provided.
