## Is volume the same as mass in water?

The density of a material is defined as its mass per unit volume. In this example, each volume of water is different and therefore has a specific and unique mass. The mass of water is expressed in grams (g) or kilograms (kg), and the volume is measured in liters (L), cubic centimeters (cm3), or milliliters (mL).

**How do you find the volume with mass and water?**

Subtract the weight of the container to get the weight of the liquid. Look up or calculate the density of the liquid, then determine the volume of the liquid by dividing the mass of the liquid by the density.

**Will plasticine sink in water?**

This extra water pushed aside means that the upthrust force is much greater on the plasticine (Archimedes’ principle), and it will float. It is air enclosed within the boat shape, therefore, that causes the boat to float.

### How do you find mass with volume?

Volume equals mass divided by density; and. Mass equals density times volume.

**How is volume calculated?**

Whereas the basic formula for the area of a rectangular shape is length × width, the basic formula for volume is length × width × height.

**How do I find the volume?**

#### How do you find the mass of water in a hydrate?

The mass of water in the hydrate is the coefficient (6) multiplied by the molar mass of H2O. The molar mass of the hydrate is the molar mass of the CoCl2 plus the mass of water.

**How do you determine water weight?**

To find the weight of water, start by finding the density(1 kg/L at 39.2°) and the volume of water. Convert the volume of water to liters and then multiply by the density to find the weight.

**What do you think if this plasticine ball was put into water will it sink Why?**

Yes! It sinks because the material is more dense than water. What do you think will happen if you drop a ball of plasticine into water? This time, change the shape of the ball into a boat shape.

## How do you calculate the density of plasticine?

But we know that A, B and C are all equal to 0. You can resolve this by making these constants zero then adjusting D to make the line fit using the + and – buttons . The equation will now be of the form M = Dd3 where D = πρ/6. Use your value of D to calculate the density of the plasticine, ρ.

**How do you find the volume of water?**

Finding Volume. If the object fits into a graduated cylinder or a measuring cup, you can read the measurement directly. If the water level starts at 40 ml and changes to 90 ml after submerging the object, the volume of the object equals final water volume (90 ml) minus initial water volume (40 ml), or 50 ml.

**How is water displacement used to measure mass?**

Measure mass using balance scales. The water displacement method measures the volume of water displaced by an object. The change in volume of water when an object is submerged equals the volume of the object. Sciencing_Icons_Science SCIENCE

### How to calculate density using mass and volume?

Demonstrate how to calculate density (D = m/v) by dividing the mass by the volume. Point out that that the answer will be in grams per cubic centimeter (g/cm 3 ). Give one activity sheet to each student. Students will record their observations and answer questions about the activity on the activity sheet.
