Answer:
The empirical formula of the compound is CH
Explanation:
We are provided with the information that C has 92% and H has 8% in the compound
Note % is also written in mass ie grams(g)
Molar mass of C - 12.0107
Molar mass of H - 1.00784
C. H
92g. 8g
Divided by the number of molar mass to get the number of moles
92g. 8g
12.0107. 1.00784
= 7.6598. = 7.9378
Divide through by the number of mole that has the lowest value
7.6598/7.6598 7.9378/7.6598
= 1. = 1.363
Therefore C has 1 = 1
H has 1.363 = 1
The empirical formula = CH
