Answer:
C₇H₃Cl₂N
Step-by-step explanation:
To determine the empirical formula of DCBN, we need to follow a series of steps.
Step 1: Divide the percent composition of each element by its molar mass
C: 48.9/12.01 = 4.07
H: 1.76/1.01 = 1.76
Cl: 41.2/35.45 = 1.16
N: 8.15/14.01 = 0.582
Step 2: Divide all the numbers by the smallest one
C: 4.07/0.582 ≈ 7
H: 1.76/0.582 ≈ 3
Cl: 1.16/0.582 ≈ 2
N: 0.582/0.582 = 1
The empirical formula of DCBN is C₇H₃Cl₂N
