## How do you find the mass when given moles?

If mass is given in kilograms (kg), multiply it by 1,000 to give a mass in grams (g). Substitute in the values and solve the equation to find moles of substances (mol).

Calculating the Moles of a Pure Substance (n=m/M)

we know the mass with units of grams (g)
we know the molar mass with units of grams per mole (g mol1)

## How do you find mass from volume?

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

## How do you calculate mass in chemistry?

MASS OF A SUBSTANCE = VOLUME X DENSITY.

## 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 does n m/m mean?

n = m/M n is the amount of substance, in moles, mol. m is the mass of the substance, in grams, g. M is the molar mass of the substance (the mass of one mole of the substance) in g mol-1. Molar masses: These. will be given in.

## How do you calculate relative formula mass?

Relative atomic masses can be used to find the relative formula mass of a compound. To find the relative formula mass (M r) of a compound, you add together the relative atomic mass values (A r values) for all the atoms in its formula.
