I need help giving 45 points. Wut does V mean

11) A student performs an experiment with three unknown fluids and obtains the following measurements:

Fluid A: m = 2060 g, V = 2000 mL, D =

Fluid B: m = 672 g, V = 850 mL , D =

Fluid C: m = 990 g, V = 1100 mL, D =

im guessing volume. i really dont know but my guess would be volume

substituting a hydrogen atom with a halogen in a hydrocarbon:

- the single bond remains single. a is wrong.

- the bond with hydrogen is as strong as with a halogen. c is wrong

- a hydrocarbon is saturated if there is no double bond. we do not know that so d is wrong.

- carbon will always have four valence electrons. e is wrong.

by elimination, the correct answer is b. the boiling point of the new compound increases.
