We’re being asked to determine the empirical formula of a compound composed of N and O, given the mass percent of N and O.
Recall that the empirical formula is the simplest whole-number ratio formula of a compound.
For this problem, we need to do the following steps:
Step 1: Calculate the mass and moles of N and O in the compound.
Step 2: Determine the lowest whole number ratio of N and O to get the empirical formula.
A sample of an unknown contains 30.4% nitrogen and 69.6% oxygen. What is the empirical formula for this compound?
