# How would you measure the mass and volume of a substance?

## How would you measure the mass and volume of a substance?

For both solids and liquids, a balance can be used to measure mass; however, methods for determining volume are different for solids and liquids. As liquids can flow and take the shapes of their containers, glassware such as a graduated cylinder or volumetric flask can be used to measure the volume of a liquid.

## What is the relationship between the volume of a substance and its mass?

We can say that the volume of the object is directly proportional to its mass. As the volume increases the mass of the object increases in direct proportion.

How do you find the mass of a substance or an object?

Mass is a measure of the amount of matter in a substance or an object. The basic SI unit for mass is the kilogram (kg), but smaller masses may be measured in grams (g). To measure mass, you would use a balance.

What would you use to measure the mass of an object?

For the majority of everyday objects, a balance is used to determine an object’s mass. The balance compares an object with a known mass to the object in question. Different types of balances include digital scientific balances and beam balances, such as a triple beam balance.

### What is used to measure the mass of a substance?

balance
To measure mass, you would use a balance. In the lab, mass may be measured with a triple beam balance or an electronic balance, but the old-fashioned balance pictured below may give you a better idea of what mass is.

### How do you find the mass of an object with the volume?

If you know the density of the material from which the object is made, you can find the volume simply by weighing the object. Since density = mass ÷ volume; volume = mass ÷ density.

How would you measure the mass and weight of an object?

To find an object’s mass using its weight, the formula is Mass equals Weight divided by the Acceleration of Gravity (M = W ÷ G). Convert the weight measured in pounds to the equivalent in Newtons. In the formula for determining mass based on weight, mass is measured in Newtons.

What is the relation between volume and mass?

The relationship between volume and mass exists if you also know the density. The formula for the relationship between mass, volume and density is as follows: mass = density * volume.

## How is the density of a substance measured?

Density is how tightly packed the atoms and molecules in a substance are, measured in kilograms per meter cubed. If you have a lot of mass in a small area, that’s high density. If you have little mass spread over a large area, that’s low density.

## When to use standard units of mass or volume?

But sometimes people can use non-standard or non-scientific units. For example, if someone uses a mass in grams, and a volume in centimeters cubed, then the density will come out in grams per cubic centimeter. But, sometimes you’ll want to be a good scientist and use standard units instead.

Why are mass density and volume important in chemistry?

All of these — mass, density, and volume — are simple concepts, yet in order to work in chemistry or any of the other hard sciences, it is essential to understand these types of measurement. Measuring density, for instance, aids in determining the composition of a given substance, while volume is a necessary component to using the gas laws.
