Mass of a 25 mL Round Bottom Flask

25 mL Round Bottom Flask Mass in grams

a) 10.0 g

b) 15.6 g

c) 20.2 g

d) 25.0 g

Final answer:

The correct answer for the mass of a 25 mL round bottom flask is 10.0 g.

Explanation:

In the question, a student is given the options of (a) 10.0 g, (b) 15.6 g, (c) 20.2 g, and (d) 25.0 g for the mass of a 25 mL round bottom flask.

To determine the correct answer, we need to understand that the mass of the flask will depend on its density. The density is calculated by dividing the mass (g) by the volume (mL).

Let's consider each option:

• (a) 10.0 g: If the flask has a density of 0.4 g/mL, then the mass would be 25 mL * 0.4 g/mL = 10 g. So, this option is the correct answer.
• (b) 15.6 g: This option does not match the calculated mass for a density of 0.4 g/mL.
• (c) 20.2 g: This option does not match the calculated mass for a density of 0.4 g/mL.
• (d) 25.0 g: This option does not match the calculated mass for a density of 0.4 g/mL.

Therefore, the correct answer is (a) 10.0 g.
