Question

A weigh bottle has a mass of 10. 254 g. When distilled water from a 25-ml transfer pipet is added to the weigh bottle the mass is 35. 131 g at 25 °c. What is the true volume of the 25-ml pipet at 25 °c?.

Answer 1

A 25-mL pipet, with a true volume of 24.95 mL, is used to transfer distilled water to a 10.254-g weigh bottle, increasing its mass to 35.131 g at 25 °C.

• Step 1: Calculate the mass of water transferred.

A weigh bottle has a mass of 10.254 g and a mass of 35.131 g when distilled water is transferred from a 25-mL pipet. The mass of water is the difference between these 2 values.

m = 35.131 g - 10.254 g = 24.877 g

What is density?

Density is the ratio between mass (m) and volume (V).

• Step 2: Calculate the volume corresponding to 24.877 g of water at 25 °C.

The density of water at 25 °C is 0.9970 g/mL.

24.877 g × 1 mL/0.9970 g = 24.95 mL

A 25-mL pipet, with a true volume of 24.95 mL, is used to transfer distilled water to a 10.254-g weigh bottle, increasing its mass to 35.131 g at 25 °C.
