the mass of an empty container is measured and found to be 55.75g. the container is filled to thee rim with water. its mass is measured again and found to be 105.75g. The container is emptied and dried with paper towel to remove any traces of water. It is then filled with an unknown liquid., The new mass is 123.75g. Use calculations to determine if the unknown liquid is cooking oil or corn syrup.

Question

WATER - 1.00 DENSITY (g/cm3
COOKING OIL - 0.894 Density (g/cm3
Corn syrup 1.36 density g/cm3

if u can help me solve this plz!

Answer 1

mass of water = 105.75 - 55.75 = 50 g
so volume of water = 50 g (1 cm^3/g) = 50 cm^3 = vol of bottle
mass of stuff = 123.75 - 55.75 = 68 g
density of stuff = 68 g /50 cm^3 = 1.36 g/cm^3

Answer 2

Thanks!

Answer 3

no calculation needed.
The new liquid is heavier than the water.
Only one of the choices is heavier than water.

It would have been a better question if several heavier liquids had been offered.
