Question

a compound has Empirical formula C2H2O if the experimental molecular weight is found to be in range 16-17 what is its molecular formula
solution:????​

Answer 1

answer:

C8H804

explanation:

i hope its help you.

Answer 2

Answer:

C8H8O4

Explanation:

There's a typo in question in PMC Practice Test.

Molecular Mass Range is 160-170.

C2H2O = 42

Given range is 160-170 (take avg. 165)

$n = \frac{165}{42} = 4.$

Multiply C2H2O with 4, you get C8H8O4
