What is the atomic mass of 26\% nitrogen and 74\% oxygen?
A chemical compound that contains 26 \% nitrogen and 74 \% oxygen has an atomic mass of 108 g/mol. What is the molecular formula of this compound? Was this answer helpful?
What is the formula for the compound with molecular mass 26g?
Assume that there are 100g of the compound. That means there will be 26g oxygen and 74g nitrogen in the compound. Molecular masses of Oxygen and Nitrogen are 16 and 14 respectively. Now you divide both with the lowest mol value, which in this case is O. So the formula will be (N3.25 O).
What is the empirical formula of nitrogen and oxygen?
Molecular masses of Oxygen and Nitrogen are 16 and 14 respectively. So the formula will be (N3.25 O). This is the empirical formula. If you have the molar mass, you can find the molecular formula. However, I think the question should be 74\% Oxygen and 26\% Nitrogen.
What is the formula for the molecular mass of oxygen?
Molecular masses of Oxygen and Nitrogen are 16 and 14 respectively. Moles of O = 26/16 = 1.625 mol. Moles of N = 74/14 = 5.285 mol. Now you divide both with the lowest mol value, which in this case is O. O=1. N=5.285/1.625=3.25. So the formula will be (N3.25 O).
