Question

When compound A is broken apart, it is found to contain 5.46 g of nitrogen and 6.24 g of oxygen. Compound B is decomposed into 4.99 g of nitrogen and 11.41 g of oxygen. Find the mass percent of nitrogen in each compound. Are they the same compound? Explain.

Answer 1

The mass percent of nitrogen in compound A is 46.6%, while in compound B it is 30.4%. Therefore, they are not the same compound.

Step-by-step explanation:

To find the mass percent of nitrogen in each compound, we need to determine the ratio of nitrogen's mass to the total mass of the compound, and then multiply it by 100. For compound A, the mass percent of nitrogen is (5.46 g / (5.46 g + 6.24 g)) * 100 = 46.6%. For compound B, the mass percent of nitrogen is (4.99 g / (4.99 g + 11.41 g)) * 100 = 30.4%.

The compounds have different mass percentages of nitrogen, therefore they are not the same compound. Compound A has a higher mass percent of nitrogen compared to compound B.
