What is the molecular formula of a substance that decomposes into 133 g of H and 21.3 g of O, and was found to have a molar mass of 34.1 g?
2 Answers
error in your question!
Explanation:
from molar mass the logical answer is H2O2 (likely) ...
molar mass is 34
atomic mass of O is 16
atomic mass of H is 1
the only realistic combination of this is 2 x O + 2 x H, H2O2.
From your data you get a weird formula of H99O1 (unlikely) ....
Surely you mean
Explanation:
Let us suppose that there were
And thus we gets an empirical formula of
But we know that the
And thus
Clearly
