How do we measure the mass and volume of liquids?

How do we measure the mass and volume of liquids?

We calculate the mass volume of a liquid by dividing the measure of his mass (g) by that of his volume (mL) . We measure the mass of one liquid unknown using a balance and we obtain a mass of 25.2 g. Then we measure the volume from liquid using a graduated cylinder and we obtain a volume of 18mL.

What is the formula for calculating the mass of a liquid?

Calculate the mass volume (ρ) of the liquid unknown using of the formula ρ=m/v. 4.

How do you determine the volume of a liquid?

To measure the volume of a liquid, you can use any container with graduations or a gauge line (beaker, Erlenmeyer, volumetric flask), but the best suited is the graduated cylinder. In a graduated cylinder, the free surface of the liquid takes the form of a meniscus.

How to measure the mass of a solid body?

Handling

1. Handling. Weigh the weighing boat using the balance. Note the mass.
2. To put the solid to be weighed in the basket on the scale pan.
3. Weigh the basket and the solid. Note the mass.
4. Calculate the mass from solid to weigh. Reset the scale cursors to zero.

What is the unit of density?

The unit in the international system of density is kilogram per cubic meter denoted kg/m 3 (if the mass in “kg” and the volume in “m 3”). We often use the gram per cubic centimeter noted g/cm 3 (if the mass in “g” and the volume in “cm 3”)

How to calculate the density of a body?

The density of a body is a physical quantity which represents the mass of a unit of Volume, also equal to the ratio of the mass m to the volume V of this body. The unit in the international system of density is kilogram per cubic meter denoted kg/m 3 (if the mass in “kg” and the volume in “m 3”).

How do you measure mass?

Mass is measured with a balance. The legal unit is the kilogram (symbol: kg). Method for using a scale: If an object has been placed on the scale, the mass is displayed. If you have placed a container and want to weigh a liquid, use the “TARE” function. By pressing this button, the container is on the scale but it displays 0.

What is the difference between mass and volume?

Mass and Volume Course. Summary. The mass and the volume of a body indicate respectively the quantity of matter which composes it and the space which it occupies. These two quantities can be expressed with several units, it is therefore necessary to know how to convert them.
