Density: A Comprehensive Guide to Converting mL to g

Introduction

Density is a fundamental property of matter that measures the mass of a substance per unit volume. In many applications, it is necessary to convert between units of volume, such as milliliters (mL), and units of mass, such as grams (g). This article provides a detailed guide to understanding density and performing accurate conversions between mL and g.

Understanding Density

Density is defined as the mass of a substance divided by its volume. The SI unit of density is kilograms per cubic meter (kg/m^3). However, other units, such as grams per cubic centimeter (g/cm^3) and grams per milliliter (g/mL), are also commonly used.

Calculating Density

density ml to g

The formula for calculating density is:

Density: A Comprehensive Guide to Converting mL to g

density = mass / volume

where:

density is the mass of the substance per unit volume
mass is the total mass of the substance
volume is the total volume of the substance

To convert from mL to g, multiply the volume in mL by the density in g/mL.

Understanding Density

Substance	Density (g/mL)
Water	1.00
Ethanol	0.789
Olive oil	0.916
Mercury	13.595
Gold	19.32

Applications of Density

Density plays a vital role in various applications, including:

Introduction

1. Determining Purity

The density of a substance can be used to determine its purity. For example, the density of pure water is 1.00 g/mL. If the density of a water sample is less than 1.00 g/mL, it indicates the presence of impurities.

2. Identifying Substances

The density of a substance can help identify it. For example, the density of gold is 19.32 g/mL, which is significantly higher than the density of other metals.

3. Calculating Mass and Volume

If the density and volume of a substance are known, its mass can be calculated using the formula:

mass = density * volume

Similarly, if the density and mass of a substance are known, its volume can be calculated using the formula:

volume = mass / density
