PPM to Moles Calculator

Formula

To calculate the conversion from ppm to moles:

\[ M = \frac{C \cdot V}{MW} \]

Where:

\(M\) is the amount of substance in moles
\(C\) is the concentration in parts per million (ppm)
\(V\) is the volume of the solution (L)
\(MW\) is the molecular weight of the substance (g/mol)

What is PPM to Moles?

PPM to moles is a conversion process used in chemistry to convert a concentration given in parts per million (ppm) to moles, which is a unit of measurement for the amount of a substance. This conversion is often necessary when dealing with solutions or mixtures, as it allows for a more accurate understanding of the quantity of a specific substance within a larger mixture. The conversion typically involves knowing the volume of the solution and the molecular weight of the substance.

Example Calculation 1

Let's assume the following values:

Concentration (\(C\)) = 100 ppm
Volume (\(V\)) = 1 L
Molecular Weight (\(MW\)) = 50 g/mol

Using the formula:

\[ M = \frac{100 \cdot 1}{50} = 2 \]

The amount of substance is 2 moles.

Example Calculation 2

Let's assume the following values:

Concentration (\(C\)) = 200 ppm
Volume (\(V\)) = 2 L
Molecular Weight (\(MW\)) = 100 g/mol

Using the formula:

\[ M = \frac{200 \cdot 2}{100} = 4 \]

The amount of substance is 4 moles.
