Would it not be
Explanation:
The molecular formula is always a whole number multiple of the empirical formula....we were quoted an empirical formula of
CLEARLY
Explanation:
First, find the mass of the empirical formula:
Divide the molecular formula's mass by the empirical formula's mass:
You can round
Finally, multiply each term in the empirical formula by
The answer is
Explanation:
Here the empirical formula is
It must be clear that the molecular formula is gonna be some factor of the empirical formula given, and let's suppose that factor
Thus:
Mass of
or, Mass
So,
So, Molecular formula =
