Final answer:
The molecular formula for the compound made up of 30.45 g N and 69.55 g O, and has a formula mass of 92.02 amu is N₂O₄.
Therefore, the correct answer is d) N₂O₄.
Step-by-step explanation:
The molecular formula for the compound that is made up of 30.45 g N and 69.55 g O, and has a formula mass of 92.02 amu is d) N₂O₄.
To determine the molecular formula, we first need to calculate the number of moles of each element. Then, we divide the moles of each element by the smallest number of moles to find the simplest ratio of the elements. In this case, the simplest ratio is N₂O₄, which has a formula mass of 92.02 amu and satisfies the given masses of nitrogen and oxygen.
