## Which tool can be used to measure the volume of liquid?

Volumetric cylinders and volumetric flasks are used to measure volume of liquids contained in them. They are calibrated for volume included in them – this is indicated by the marking “IN”. The liquid has accurate volume when it reaches the corresponding marking on the scale. Volume is usually indicated in mL.

## Which is the most accurate method for measuring volumes of liquids a beaker or a graduated cylinder?

Graduated cylinders are generally more accurate and precise than laboratory flasks and beakers, but they should not be used to perform volumetric analysis; volumetric glassware, such as a volumetric flask or volumetric pipette, should be used, as it is even more accurate and precise.

## What is the most accurate way to measure the volume of a liquid?

1 Answer. A graduated cylinder should be more accurate than a beaker

## How do you calculate the volume of a solid?

Volume of Rectangle-Based Solids 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 you explain volume to a child?

Volume refers to the amount of space the object takes up. In other words, volume is a measure of the size of an object, just like height and width are ways to describe size. If the object is hollow (in other words, empty), volume is the amount of water it can hold….

## What is relation between mass and volume?

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.

## What is the difference between molecular mass and formula mass?

Formula mass is defined as the sum of atomic masses of the ions present in the formula unit of an ionic compound whereas molecular mass is the sum of the atomic masses of the atoms in a molecule.

## How do you calculate mol weight?

Sample Molecular Weight Calculation Using the periodic table of the elements to find atomic weights, we find that hydrogen has an atomic weight of 1, and oxygen’s is 16. In order to calculate the molecular weight of one water molecule, we add the contributions from each atom; that is, 2(1) + 1(16) = 18 grams/mole.

## How do you find formula weight?

From the formula and the atomic mass of the atoms you can find the formula weight or molecular mass for the compound. To calculate the formula weight for a compound we will select the atomic mass of each of the elements in the compound from the periodic table, multiply by the number of atoms, and sum the result.

## How do you find the formula for an unknown compound?

Divide the molar mass of the compound by the empirical formula mass. The result should be a whole number or very close to a whole number. Multiply all the subscripts in the empirical formula by the whole number found in step 2. The result is the molecular formula.
