# What is the density of corn syrup in g cm3?

Corn syrup is a popular sweetener used in many food products. It is a viscous, thick liquid made from corn starch. Understanding the density of corn syrup is important for measuring out the correct amounts when cooking or baking. This article will examine the density of corn syrup and provide a detailed answer to the question “What is the density of corn syrup in g/cm3?”

## What is Density?

Density measures the mass of a substance per unit of volume. It is calculated by dividing the mass of the substance by its volume. The standard unit for density is g/cm3 or grams per cubic centimeter.

Density provides important information about the properties of a substance. Substances with higher densities, like metals, will sink in water, while substances with lower densities, like wood, will float. Density also tells you how much mass is contained in a certain volume of a substance.

## Factors Affecting the Density of Corn Syrup

Several factors impact the density of corn syrup:

### 1. Composition

Corn syrup is made up of glucose sugars extracted from corn starch. The specific glucose sugars that make up corn syrup include maltose, maltotriose, and higher glucose polymers. The varying proportions of these glucose sugars can result in corn syrup batches with slightly different densities.

### 2. Moisture Content

Corn syrup contains water in addition to glucose sugars. Syrup with higher moisture content will be less dense than syrups with lower moisture levels. Most corn syrups contain approximately 30% water.

### 3. Temperature

Temperature impacts the density of corn syrup. As corn syrup is heated, the molecules spread out becoming less dense. As it cools, the molecules contract, increasing density. Density should be measured at standard room temperature.

### 4. Purity

The purer the corn syrup, the higher the density. Impurities like salts, flavorings, and colors will lower the overall density slightly. Most commercially available corn syrups are relatively pure with few additives.

## Typical Density of Corn Syrup

The density of pure corn syrup generally ranges from 1.3 – 1.4 g/cm3. However, common table syrup and pancake syrup have slightly lower densities due to added water and flavorings.

Here are some typical corn syrup density values:

 Type of Corn Syrup Density (g/cm3) Pure corn syrup 1.37 – 1.43 Table syrup 1.32 – 1.38 Pancake syrup 1.28 – 1.34

As you can see, the density declines slightly as more water and flavorings are added to create consumer corn syrup products. But overall, the density remains relatively high because of the dense glucose sugars that make up the majority of corn syrup.

## Measuring the Density of Corn Syrup

To measure the density of corn syrup yourself, follow this simple procedure:

### Materials

– Corn syrup sample
– Triple beam balance or digital scale
– Calculator

### Procedure

1. Pour 100 mL of corn syrup into a graduated cylinder.
2. Weigh the cylinder with the corn syrup sample on a scale. Record this mass measurement.
3. Subtract the mass of the empty graduated cylinder from the mass with the sample to find the mass of just the corn syrup.
4. Divide the mass of the corn syrup by the volume of 100 mL.
5. The resulting number is the density in g/mL. Convert to g/cm3 by multiplying by 1 cm3/1 mL.

### Calculation

Corn syrup mass: 152 g

Corn syrup mass = Total – Cylinder mass

= 152 g – 62 g

= 90 g

Volume = 100 mL = 100 cm3

Density = Mass / Volume

= 90 g / 100 cm3

= 0.9 g/cm3

So for this sample, the measured density of corn syrup is 0.9 g/cm3.

## Uses for Corn Syrup Density Information

Knowing the density of corn syrup has several practical applications:

– Baking – Measuring correct amounts of corn syrup by weight for recipes.

– Shipping – Determining weights and volumes needed for transporting corn syrup.

– Processing – Applying the optimal heat and vacuum pressures to achieve the desired density during manufacturing.

– Quality Control – Using density measurements to monitor purity and consistency between batches.

– Research – Investigating how chemical changes impact corn syrup density.

So whether you’re shipping tankers of corn syrup or baking up a batch of cookies, knowing the density of corn syrup helps ensure you’re using the correct quantities for your needs.

## Conclusion

In summary, the standard density of pure corn syrup ranges from 1.3 – 1.4 g/cm3 depending on exact composition and moisture content. Table syrup and pancake syrup are slightly less dense, ranging from 1.28-1.38 g/cm3 due to added water and flavorings. The density of corn syrup can be precisely measured by weighing a known volume of sample. This density information is useful for commercial production, cooking, and research applications. So next time you pour corn syrup over a stack of pancakes, you can impress your friends by knowing the exact density!
