Question

A. If 15 ml of a liquid has a mass of 11.85 grams,

(1) What is the density?
(2) What is the liquid?

Answer 1

1. 0.79g/mL

2. Ethanol

Step-by-step explanation:

The density of a substance can be calculated by using the formula;

Density (g/mL) = mass (g) ÷ volume (mL)

According to the information provided in the question, mass = 11.85grams, volume = 15mL.

Hence, density = 11.85g ÷ 15mL

= 0.79

Density of the liquid = 0.79g/mL.

Substances usually have their own unique density, which is one of the properties that distinguish them. In this case, ETHANOL is the liquid that possesses a density of 0.79g/mL.
