The formula of nitrobenzene is C₆H₅NO₂. The molecular weight of this compound is amu. A) 109.10 B) 43.03 C) 123.11 D) 107.11 E) 3.06

Question

Quizplus · Accepted Answer

The molecular weight of a compound is calculated by adding the atomic weights of all the atoms present in the compound. Using a periodic table, the atomic weights of carbon, hydrogen, oxygen, and nitrogen are found to be 12.01, 1.01, 16.00, and 14.01, respectively. Counting the number of atoms of each element in the formula, the molecular weight is calculated as follows:

(6 x 12.01) + (5 x 1.01) + 2 x 16.00 + 1 x 14.01 = 123.11 amu

Therefore, the correct answer is C.

The Formula of Nitrobenzene Is C6H5NO2
