# How to convert density from mol/L to kg/m3?

• Stupid_Engine
In summary, to convert density from mol/L to kg/m3, you need to first convert the moles to grams by using the molecular weight of the substance. Then, you need to convert from L to m^3 by multiplying by 1000. There is no single conversion factor, so the specific molecular weight and density of the substance must be used in the calculation. As an example, the conversion for air with a molecular weight of 28.84 g/mole and a density of 1.2 kg/m^3 would result in a density of 1.2/28.84 moles/L.

How to convert density from mol/L to kg/m3?

Let the units be your guide...You need to convert the moles to gram by using the molecular weight of whatever you are looking at. The conversion to m^3 from L is 1000, i.e. there are 1000 L in one m^3. So your conversion should look like

$$\left[\frac{mol}{L}\right] \left[\frac{MW}{mol}\right]\left[\frac{kg}{1000 g}\right] \left[\frac{1000 L}{m^3}\right]$$

Main point is that there is no magic conversion factor like 2.54 or something like that.
example
MW of Air is about 28.84 g/mole
The density of air is 1.2 kg/m^3
so that is 1200 grams/m^3
so that is 1200/28.84 moles /m^3
so that is 1.2/28.84 moles/L

## 1. What is the formula for converting density from mol/L to kg/m3?

The formula for converting density from mol/L to kg/m3 is:
density (kg/m3) = molar mass (g/mol) x concentration (mol/L) x 1000.

## 2. How do I convert from mol/L to kg/m3?

To convert from mol/L to kg/m3, you need to know the molar mass of the substance, which can be found on the periodic table. Then, simply multiply the molar mass by the concentration in mol/L and by 1000.

## 3. Why do we need to convert density from mol/L to kg/m3?

Density is commonly expressed in kg/m3, which is the SI unit for density. Converting from mol/L to kg/m3 allows us to compare the density of different substances on a standardized scale.

## 4. Can I use any concentration unit to convert density from mol/L to kg/m3?

No, you cannot use any concentration unit. The concentration must be in mol/L for the conversion to be accurate. If the concentration is given in a different unit, it must be converted to mol/L first before using the formula.

## 5. Is there an online calculator or tool for converting density from mol/L to kg/m3?

Yes, there are many online calculators and tools available for converting density from mol/L to kg/m3. Some examples include the "Molar Mass Calculator" on the National Center for Biotechnology Information website, or the "Molarity to Density Calculator" on the Omni Calculator website.
