Question

An object with a

mass of 7 g and a
volume of 10 mL is
most likely what
substance?

Answer 1

Ethanol

Step-by-step explanation:

Given parameters:

Mass of the object = 7g

volume of the object = 10mL

Unknown:

The kind of substance it is = ?

Solution:

Since from the parameters, we can determine the density of the object. Density is an intensive property of substances.

So, we simply find the density and check a density table for the type of substance it is.

Density is the mass per unit volume.

Density =
`(mass)/(volume)`

Let us take the volume to cm³;

10mL = 10cm³

Density =
`(7)/(10)` = 0.7g/cm³

This is most likely ethanol
