Understanding the Problem

In this exercise, we are given a gas sample with a known volume and density. We need to calculate the mass of the gas sample using the given information. The density of the gas is given as 1.41 g/L, and the volume of the gas is 8.052 L. We will use the formula for density to solve for the mass of the gas sample.

The Formula for Density

The formula for density is:

Density = Mass / Volume

We can rearrange this formula to solve for the mass of the gas sample:

Mass = Density × Volume

Calculating the Mass of the Gas Sample

Now that we have the formula, we can plug in the given values to calculate the mass of the gas sample.

Mass = 1.41 g/L × 8.052 L

Mass = 11.37 g

Therefore, the mass of the gas sample is 11.37 g.

Conclusion

In this exercise, we used the formula for density to calculate the mass of a gas sample. We were given the density of the gas and the volume of the gas, and we were able to use these values to solve for the mass of the gas sample. This is an important concept in chemistry, as it allows us to calculate the mass of a substance using its density and volume.

Importance of Density in Chemistry

Density is an important property in chemistry, as it can be used to identify and characterize different substances. By measuring the density of a substance, we can determine its mass per unit volume, which can be useful in a variety of applications.

Frequently Asked Questions (FAQs) About Density and Mass ===========================================================

Q: What is density, and how is it related to mass and volume?

A: Density is a measure of the mass of a substance per unit volume. It is calculated by dividing the mass of the substance by its volume. The formula for density is:

Density = Mass / Volume

Q: How do I calculate the mass of a substance using its density and volume?

A: To calculate the mass of a substance using its density and volume, you can use the formula:

Mass = Density × Volume

For example, if the density of a substance is 1.41 g/L and its volume is 8.052 L, the mass of the substance would be:

Mass = 1.41 g/L × 8.052 L = 11.37 g

Q: What are some common units of density?

A: Some common units of density include:

g/L (grams per liter): This is a common unit of density for liquids and gases.
g/cm³ (grams per cubic centimeter): This is a common unit of density for solids.
kg/m³ (kilograms per cubic meter): This is a common unit of density for solids and liquids.

Q: How do I convert between different units of density?

A: To convert between different units of density, you can use the following conversion factors:

1 g/L = 1 kg/m³
1 g/cm³ = 1000 kg/m³

For example, if you want to convert a density of 1.41 g/L to kg/m³, you can multiply it by 1:

1.41 g/L × 1 = 1.41 kg/m³

Q: What are some real-world applications of density?

A: Density has many real-world applications, including:

Archaeology: Density can be used to identify the type of material used in ancient artifacts.
Forensic Science: Density can be used to identify the type of substance used in a crime scene.
Materials Science: Density can be used to identify the type of material used in a product.

Q: How do I measure the density of a substance?

A: There are several ways to measure the density of a substance, including:

Displacement Method: This method involves measuring the volume of a substance by displacing a known volume of water.
Pycnometer Method: This method involves measuring the volume of a substance using a pycnometer, which is a device that measures the volume of a substance by measuring the volume of the air displaced by the substance.
Hydrostatic Balance Method: This method involves measuring the density of a substance by measuring the weight of the substance in air and in water.

Q: What are some common mistakes to avoid when measuring density?

A: Some common mistakes to avoid when measuring density include:

Not accounting for the buoyancy of the substance: This can result in an incorrect measurement of the density of the substance.
Not using a calibrated instrument: This can result in an incorrect measurement of the density of the substance.
Not following proper laboratory procedures: This can result in an incorrect measurement of the density of the substance.

Conclusion

In conclusion, density is an important property of a substance that can be used to identify and characterize it. By understanding the formula for density and how to measure it, you can solve problems and make important discoveries in a variety of fields.
