An empty Erlenmeyer flask weights 241.3 g. When filled with water (d = 1.00 g cmଷ ⁄ ), the flask and its contents weight 489.1 g. What is the flask’s volume? What is the mass of the flask when filled with chloroform (d = 1.48 g cmଷ ⁄ )?

608 g

Explanation:

Mass of flask + contents = 489.1 g

Mass of flask = 241.3 g.

Mass of water = 489.1 - 241.3 = 247.8 g

Density of water = 1.0 g/cm^3

volume of water = 247.8 g/1.0 g/cm^3

Volume = 247.8 cm^3

But

Volume of flask = volume of water

Volume of flask = 247.8 cm^3

volume of chloroform = volume of flask

mass of chloroform = 1.48 g/cm^3× 247.8 cm^3

Mass of flask + chloroform = 366.7 g + 241.3 = 608 g
