Lol help for a brainlist (must show work ) Jira told Helen that the perfume she used was less dense than water. Helen got a graduated cylinder from the cabinet and found the mass of the cylinder to be 58.35 g. Jira poured 25.0 mL of perfume into the cylinder and massed it again. The combined mass of the cylinder and perfume was 68.80 g.
What was the mass of the perfume?

What was the density of the perfume?

If water’s density is 1.0 g/mL, then would the perfume be more or less dense than water? Would the perfume float on top or sink to the bottom of the water?
