# What is the density of a substance that has a mass of 45 grams and a volume of 30 ml?

## What is the density of a substance that has a mass of 45 grams and a volume of 30 ml?

Density is mass divided by volume, so that the density is 45 g divided by 15cm3, which is 3.0 g/cm3. Problem 2: You have a different rock with a volume of 30cm3 and a mass of 60g. What is its density? Density is mass divided by volume, so that the density is 60 g divided by 30cm3, which is 2.0 g/cm3.

### How do you find the density with mass and volume?

The formula for density is d = M/V, where d is density, M is mass, and V is volume. Density is commonly expressed in units of grams per cubic centimetre. For example, the density of water is 1 gram per cubic centimetre, and Earth’s density is 5.51 grams per cubic centimetre.

#### What is the density of an object with a mass of 5g and a volume of 2.5 ml?

Thus, the substance has a density of 0.5gcm3 .

How do you find the volume when given the mass and volume?

Divide the mass by the density of the substance to determine the volume (mass/density = volume). Remember to keep the units of measure consistent. For example, if the density is given in grams per cubic centimeter, then measure the mass in grams and give the volume in cubic centimeters.

What is the density of an object with a mass of 25 grams and volume of 37 cubic centimeters?

The answer is 2.5 g/cm3 .

## How do you calculate mass density?

The formula for density is the mass of an object divided by its volume. In equation form, that’s d = m/v , where d is the density, m is the mass and v is the volume of the object. The standard units are kg/m³.

### How do you calculate mass in chemistry?

MASS OF A SUBSTANCE = VOLUME X DENSITY.

#### How do I find the density of an object?

How do you calculate the mass of an object?

One way to calculate mass: Mass = volume × density. Weight is the measure of the gravitational force acting on a mass. The SI unit of mass is “kilogram”.

How do you find mass when given volume and molar mass?

If you have a pure liquid or a solid, you use its density to calculate its mass and then divide the mass by the molar mass. If you have a solution, you multiply the molarity by the volume in litres. There are two steps: Multiply the volume by the density to get the mass.

## What is the mass and volume?

Mass is how much stuff something is made of. Volume is how much space an object takes up. Find two objects with similar MASS.

### What is the density of an object whose volume is 25 mL and whose mass is 5g?

fruity · Stefan V. The answer is 2.5 g/cm3 .

#### What is the difference between mass and volume in chemistry?

When solving for mass you need to know volume and density while when solving for volume you need to know the substance’s mass and density. The output if calculating density is in grams per cm 3 or kg per m 3, as well as in oz/cu in, lb/cu ft and lb per cubic yard.

What is mass density?

Mass density is defined as the ratio of the substance’s volume to its mass. The calculator can also be used to solve for any of the other values: mass and volume. When solving for mass you need to know volume and density while when solving for volume you need to know the substance’s mass and density.

What is the output when solving for volume and mass?

When solving for mass you need to know volume and density while when solving for volume you need to know the substance’s mass and density. The output if calculating density is in grams per cm 3 or kg per m 3, as well as in oz/cu in, lb/cu ft and lb per cubic yard. Grams or kilograms per litre are also available.

## What is the density of a 25 cm3 sample?

The density of a substance is 4.0 g/cm3. If a sample of the substance has a volume of 25 cm3, then what is its mass? You have a lead ball with a mass of 420 g. The density of lead is 10.5 g/cm3.
