The percentage composition of sulphur in the unknown compound can be calculated as follows:
Mass of sulphur = 2.60 g
Mass of unknown compound = 5 g
Percentage of sulphur = (Mass of sulphur / Mass of unknown compound) x 100
= (2.60 g / 5 g) x 100
= 52%
Therefore, the percentage composition of sulphur in the unknown compound is 52%. Answer: \boxed{52\%}.
To calculate the percentage composition of sulfur in the compound, we need to determine the total mass of the compound and the mass of sulfur in the compound.
Total mass of the compound = mass of sulfur + mass of hydrogen + mass of carbon
Total mass of the compound = 2.60 g + 0.50 g + 1.90 g
Total mass of the compound = 5.00 g
Mass percentage of sulfur = (mass of sulfur / total mass of the compound) × 100%
Mass percentage of sulfur = (2.60 g / 5.00 g) × 100%
Mass percentage of sulfur = 0.52 × 100%
Mass percentage of sulfur = 52%
Therefore, the percentage composition of sulfur in the compound is 52%.
