QUESTION:
A 0.370-mol sample of a metal oxide(\(\mathrm{M}_{2} \mathrm{O}_{3}\)) weighs 55.4 g.
(a) How many moles of O are in the sample?
(b) How many grams of M are in the sample?
(c) What element is represented by the symbol M?
ANSWER:
Step 1 of 3
Here, we are calculating the each of the following.
a.)
Let’s calculate the moles of O in
Given
The number of Moles of = 0.370 mol
From the given formula, In the sample have 2 moles of M and 3 moles of O.
0.370 mol
= 1.11 mol of O
Therefore, 1.11 mol of O are in the sample of .
