calculate the percentage of nitrogen in the compound nh3. enter the correct number in the box. the answer should be rounded to the nearest tenth. %
Answer
Explanation:
Step1: Find atomic masses
The atomic mass of nitrogen (N) is approximately 14 g/mol, and the atomic mass of hydrogen (H) is approximately 1 g/mol.
Step2: Calculate molar - mass of NH₃
The molar - mass of NH₃ ($M_{NH_3}$) is $M_{NH_3}=14 + 3\times1=17$ g/mol.
Step3: Calculate percentage of nitrogen
The percentage of nitrogen in NH₃ is $\frac{14}{17}\times100%$. $\frac{14}{17}\times100=\frac{1400}{17}\approx82.4%$
Answer:
82.4
