50 mL of 1M oxalic acid is shaken with 0.5 g of wood charcoal. The final concentration of the solution after adsorption is 0.6 M. Calculate the amount of oxalic acid adsorbed per gram of charcoal.

Explanation

To solve the problem of calculating the amount of oxalic acid adsorbed per gram of charcoal, we can follow these steps:

### Step 1: Calculate the initial amount of oxalic acid before adsorption
We know the molarity (M) of oxalic acid and the volume (V) of the solution. The formula for calculating the amount of solute (in grams) is:

\[ \text{Mass (g)} = \text{Molarity (M)} \times \text{Molar Mass (g/mol)} \times \frac{\text{Volume (mL)}}{1000} \]
