# Given a solution in moles per litre how would you convert to parts per million)ppm.)

could you help,no other information given apart from solution contains a known concentation of aluminium

mols/L. Convert mols to grams. That will be grams per 1000 mL. Convert that to mg/L. That will be ppm assuming the concentration is not too high.

## To convert a solution concentration in moles per litre (mol/L) to parts per million (ppm), you can follow these steps:

1. Start by converting the concentration in moles per litre (mol/L) to grams per litre (g/L). This can be done by multiplying the concentration in mol/L by the molar mass of the substance.

2. Convert grams per litre (g/L) to milligrams per litre (mg/L). This can be done by multiplying the concentration in g/L by 1000.

3. Finally, convert milligrams per litre (mg/L) to parts per million (ppm). This can be done by dividing the concentration in mg/L by the density of the solution and multiplying by 1000.

Since you mentioned that the solution contains a known concentration of aluminium, you will need to know the molar mass of aluminium and the density of the solution in order to perform the conversion accurately.
