Answer:

1) A flask that weighs 345.8 g is filled with 225 ml of carbon tetrachloride. The weight of the flask and carbon tetrachloride is found to be 703.55 g. From this information, calculate the density of carbon tetrachloride.

2) volume of a block is 5 cm3. If the density of the block is 250 g/cm3, what is the mass of the block?

3) A cork has a volume 25 cm3. The density of the cork is 0.25 g/cm-3. Find the mass of the cork?
