Question

A weight of 22.25g was obtained when 10-mL of water at 27C was pipet to empty Erlenmeyer flask. What was the volume delivered by the pipet?

Answer 1

Answer #1

According to the question 10 ml of water is being delivered to Erlenmeyer flask by pipet. Hence a volume of 10 ml is being delivered by the pipet.

You may be confused that how 10 ml of water is weighing 22.25 gram but 22.25 gram is the combined mass of water and 25 ml Erlenmeyer flask.

According to density of water(1 g/ml), mass of water is =10 gram

Mass of 25 ml Erlenmeyer flask= 12.25 gram

Combine mass= 22.25 gram
