1. Calculate the total mass of the compound:
* Total mass = mass of N + mass of O
* Total mass = 222.6 g + 77.4 g = 300 g
2. Calculate the percent composition of each element:
* Percent N: (mass of N / total mass) x 100%
= (222.6 g / 300 g) x 100% = 74.2%
* Percent O: (mass of O / total mass) x 100%
= (77.4 g / 300 g) x 100% = 25.8%
Therefore, the percent composition of the compound is:
* Nitrogen (N): 74.2%
* Oxygen (O): 25.8%
