# How do I go from gdm3 to mol dm 3?

## How do I go from gdm3 to mol dm 3?

Converting between units

1. to convert from mol/dm 3 to g/dm 3, multiply by the relative formula mass.
2. to convert from g/dm 3 to mol/dm 3, divide by the relative formula mass.

### How do you convert grams to moles formula?

To correctly estimate the number of moles, n , of a substance of a specific mass, m , (in grams), you need to follow the grams to moles formula: n = m / M , where, M is the molar mass of this material.

#### How do you convert grams per mole to grams per liter?

Calculate the concentration using c = n/V (remember V is always in litres) L. To convert to g L-1 you multiply the concentration by the molar mass; = 0.118 mol L-1 x 55.9 g mol-1 = 6.60 g L-1 (3 s.f.)

Is mol dm 3 the same as mol dm 3?

The SI Units of measurement for molar concentration are mol/m3. However, most chemical literature traditionally uses mol/dm3, or mol dm-3, which is the same as mol/L. mol/m3 = 10-3 mol/dm3 = 10-3 mol/L = 10-3 M = 1 mM .

What unit is g dm 3?

A measure of the amount of moles in a given volume. Conc. (mol dm-3) = moles (mol) Volume (dm3) Conc. (g dm-3) = mass (g) Volume (dm3) Page 2 Calculations in Chemistry MOLES A measure of the amount of substance. Number of = mass (m) moles (n) Molar mass (Mr) Mass is measured in grams.

## How do you find molarity from grams and volume?

As mass / volume = molarity * molar mass , then mass / (volume * molar mass) = molarity . Substitute the known values to calculate the molarity: molarity = 5 / (1.2 * 36.46) = 0.114 mol/l = 0.114 M . You can also use this molarity calculator to find the mass concentration or molar mass.

### How do you find moles from grams and volume?

There are two steps:

1. Multiply the volume by the density to get the mass.
2. Divide the mass by the molar mass to get the number of moles.

#### How do you convert moles to liters?

Converting from moles to volume (liters): Multiply your mole value by the molar volume constant, 22.4L. Converting from particles (atoms, molecules, or formula units) to moles: Divide your particle value by Avogadro’s number, 6.02×1023. Remember to use parentheses on your calculator!

Is g L same as M?

g/L is a unit of measurement of mass concentration that shows how many grams of a certain substance are present in one liter of liquid. Molarity (M) is the concentration of a solution expressed as the number of moles of solute per litre of solution.

How to convert mol DM3 to G DM-3 concentration?

multiply the mol dm-3 value by the relative molecular mass (Mr) of the chemical in solution to get the g dm-3 conc. value. Rep:? You get these gems as you gain rep from other members for making good contributions and giving helpful advice. The concentration which i have to convert is 0.403 mol dm-3 in g dm-3.
