Problem: A major textile dye manufacturer developed a new yellow dye. The dye has a percent composition of 75.95% C, 17.72% N, and 6.33% H by mass with a molar mass of about 240 g/mol. Determine the molecular formula of the dye.

🤓 Based on our data, we think this question is relevant for Professor Broome's class at University of Southern Mississippi.

FREE Expert Solution

We can assume 100g of the compound so that the % values directly translate to grams.
We then convert the mass to moles by dividing by the molar mass of the element.
