An empty erlenmeyer flask weighs

Asked by maham237 @ in Chemistry viewed by 187 People

An empty erlenmeyer flask weighs 241.3 g. when filled with water (d = 1.00 g/cm3), the flask and its contents weigh 489.1 g. what is the flask's volume? how much does the flask weigh when filled with chloroform (d = 1.48 g/cm3)?

Answered by maham237 @



The volume of the flask would simply be equal to the
volume of the water. And the mass of the water would be the difference after
and before weigh.


mass of water = 489.1 g – 241.3 g


mass of water = 247.8 g



Therefore the volume of water (which is also the volume
of the flask) is:


volume = 247.8 g / (1.00 g/cm^3)


volume = 247.8 cm^3



The total mass of the flash when filled with chloroform
would be:


total mass with chloroform = 241.3 g + 247.8 cm^3 (1.48
g/cm3)


total mass with chloroform = 608.04 g




Answers:


volume = 247.8 cm^3


total mass with chloroform = 608.04 g
