I'm taking the same quiz. The answer is column
Nitrogen trifluoride is the inorganic compound with the formula NF3. This nitrogen-fluorine compound is a colorless, odorless, nonflammable gas. It finds increasing use as an etchant in microelectronics.
(If you mean by a gas of some sort)
Answer:
8
Explanation:
From the question given above, the following data were obtained:
Empirical formula = C₅H₇
Molecular weight = 537 amu.
Number of empirical unit (n) =?
We can obtain the number of empirical units in the actual molecular formula by doing the following:
[C₅H₇]n = 537
[(12×5) + (1×7)]n = 537
[60 + 7]n = 537
67n = 537
Divide both side by 67
n = 537/67
n = 8
Thus, there are 8 empirical units in the molecular formula
Here all the following substances are not pure substances
