Calculating the Volume of a Flask

What is the volume of the internal volume of the flask?

The internal volume of the flask is 25.99mL.

When a student obtained a clean flask, she weighed the flask and stopper to find the total mass. After filling the flask with water and measuring the new mass, she found the temperature of the water to be 21ºC. Using the data provided, we can calculate the volume of the internal volume of the flask.

First, we calculate the mass of the water in the flask by subtracting the mass of the clean flask from the mass of the filled flask:

Mass water = 60.167g - 34.232g = 25.935g

Next, we convert this mass to volume using the density of water at 21ºC (0.997992g/mL):

25.935g × (1mL / 0.997992g) = 25.99mL

Therefore, the volume of the internal volume of the flask is 25.99mL.
