Question

The formula weight of ________________ is 180u.

• A. C₄H₁₂0₆
• B. C₆H₁₂O₆
• C. C₄H₃O₄
• D. C₅H₁₅O₉

Answer 1

The correct option is B

C₆H₁₂O₆

6 of C = 6 X 12 u = 72 u 12 of H = 12 X 1 u = 12 u 6 of O = 6 X 16 u = 96 u

So, sum of all three is equal to 180u i.e 72 + 12 + 96 = 180 u.Therefore option B is correct
