## How do you find mass when given weight and volume?

What Is The Formula For Mass?

1. mass=density×volume (m=ρV). Density is a measure of mass per unit of volume, so the mass of an object can be determined by multiplying density by volume.
2. mass=force÷acceleration (m=F/a). …
3. mass=weight÷gravitational acceleration (m=W/g).

## How do you find mass when given concentration and volume?

Rearranging the equation for concentration allows the mass of solute to be calculated:

1. mass of solute in g = concentration in g/dm 3 × volume in dm 3
2. A solution of sodium chloride has a concentration of 10 g/dm 3. …
3. mass of solute in g = concentration in g/dm 3 × volume in dm 3
4. = 10 g/dm 3 × 2 dm 3

## What is the mole formula?

Avogadro’s number is a very important relationship to remember: 1 mole = 6.022×1023 6.022 × 10 23 atoms, molecules, protons, etc. To convert from moles to atoms, multiply the molar amount by Avogadro’s number. To convert from atoms to moles, divide the atom amount by Avogadro’s number (or multiply by its reciprocal).

## What is formula for mass?

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 the moles of an element in a compound given mass?

Divide the mass of the compound in grams by the molar mass you just calculated. The answer is the number of moles of that mass of compound. For example, 25 grams of water equals 25/18.016 or 1.39 moles.
