Question

A liquid has a volume of 40.5 mL and a mass of 44.6 g . What is the specific gravity of the liquid?

Expert Solution

Introduction

The specific gravity of any liquid is defined as the ratio of the density of the liquid to the density of the water. The density of any liquid or material is defined as the ratio of the mass and volume of that material or liquid.

Explanation

The density of the water is one gram per milliliter roughly on the average temperature. The mass of the given liquid is 44.6g and the volume of the liquid is 40.5 ml, so the density of the liquid will be 1.101 g/ml on dividing the mass of the liquid by the volume. Now the density of the liquid is 1.101 g/ml and the density of the water is 1 g/ml, so the specific gravity (RD) of the liquid will be

$R D = \frac{ρ_{l}}{ρ_{w}}, o r R D = \frac{1.101 g / m l}{1 g / m l}, o r R D = 1.101$
