Answer:
% age of hydrogen = 17.65%
Explanation:
Given data:
Mass of ammonia = 17.0 g
Mass of hydrogen = 3.0 g
Mass of nitrogen = 14.0 g
Percentage of hydrogen = ?
Solution:
Formula:
% age of hydrogen = mass of hydrogen / mass of ammonia × 100
Now we will put the values:
% age of hydrogen = 3.0 / 17.0 × 100
% age of hydrogen = 17.65%
For oxygen:
% age of hydrogen = mass of hydrogen / mass of ammonia × 100
Now we will put the values:
% age of hydrogen = 14/ 17.0 × 100
% age of hydrogen = 82.35%
Total percentage = 17.65% + 82.35%
Total percentage = 100%
