Answer to Problem 62A
The empirical formula must be
Explanation of Solution
Given information:
- O = 7.2 x 1024 atoms
- N = 56.0 g
- H = 4.0 moles
Calculate moles of each with the help of atomic mass:
Divide by least moles to get the whole number ratio:
Thus the empirical formula must be
The empirical formula must be
