A liquid has a volume of 100 cm and a mass of 85g. The density of water is 1.0g/cm?
How does the density of the liquid compare with the density of water?
A
Its density is higher than that of water.
Its density is lower than that of water.
B
с
Its density is the same as that of water.
D
It is impossible to say with only this data.

B. Its density is lower than that of water

Explanation:

density = mass / volume

density of the liquid = 85 / 100 = 0.85 g/cm^3

now,

density of water is 1 g/cm^3 which is greater than the density of the given liquid ( 0.85 g/cm^3 )

an ion is a charged atom or molecule. it is charged because the number of electrons do not equal the number of protons in the atom or molecule. an atom can acquire a positive charge or a negative charge depending on whether the number of electrons in an atom is greater or less then the number of protons in the atom.
