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

**What Is The Formula For Mass?**

- 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.
- mass=force÷acceleration (m=F/a). …
- 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:**

- mass of solute in g = concentration in g/dm
^{3}× volume in dm^{3} - A solution of sodium chloride has a concentration of 10 g/dm
^{3}. … - mass of solute in g = concentration in g/dm
^{3}× volume in dm^{3} - = 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.

## What is the mass of a person who weighs 110 lb?

If someone says she weighs 110 pounds, think of this as her mass, which would be **50 kg** in SI units.

## What is 50n in KG?
