5)If a solution  contains 30% of sulphur, how much solution  is required to obtain 150g of sulphur?

To determine how much of the solution is required to obtain 150g of sulfur, you can use the formula:

\[
\text{Mass of solution} = \frac{\text{Mass of sulfur}}{\text{Percentage of sulfur in the solution}}
\]

Here:
- Mass of sulfur = 150g
- Percentage of sulfur in the solution = 30% = 0.30 (as a decimal)

Now, calculate the mass of the solution:

\[
\text{Mass of solution} = \frac{150g}{0.30} = 500g
\]

So, **500 grams** of the solution is required to obtain 150 grams of sulfur.
