Homework Equations
If CO = 10 moles, then how to find moles of O in CO molecule?
The Attempt at a Solution
I don't know how to proceed
From the given link, I cam to know thatjedishrfu said:Read the definition of a mole here:
https://en.wikipedia.org/wiki/Mole_(unit)
and you should be able to work this out.
Its like the old trick question of which is heavier a pound of feathers or a pound of rocks.
In the future, please provide more than I don't know as your attempt. You should research your problem and not just sit there confused. There is a way out of every maze and you can find it if you try.
I agree with the water, but what is the equation for C and O2?Indranil said:From the given link, I cam to know that
2 H2 + O2 → 2H2O implies that 2 mol dihydrogen (H2) and 1 mol dioxygen (O2) react to form 2 mol water (H2O). From this concept, I can write
1 mol C and 1-mole O2 form 1 mole of CO but how to calculate moles of O if CO = 10 moles already?
It should be C + O2 = 2COMerlin3189 said:I agree with the water, but what is the equation for C and O2?
When you've sorted that,
if 2 mole H2 and 1 mole o2 makes 2 mole H2O,
then how many moles of each is needed to make 10 mole H20 ? It's just proportion.
In 1 molecule of CO, I have 1 atom of C and 1 atom of O.jedishrfu said:A simpler set of questions are:
If I have 1 molecule of ##CO## then I know I have 1 atom of ##C## and so how many atoms of ##O## do I have?
If I have 2 molecules of ##CO## then I know I have 2 atoms of ##C## and so how many atoms of ##O## do I have?
If the ##O ## atoms combine into ##O_2## then how many ##O_2## molecules do I have?
Basically moles are a count of the number of molecules or atoms in the sample.
Like when I say I have 1 dozen eggs I know I have 12 eggs.
When I say I have 1 mole of eggs then I know I have ##6.022 x 10^{23}## (Avogadros number) of eggs.

The next question why are mole calculations so important to chemists?

Indranil said:What do you mean by 1 atom of C? Does it mean 1 mol of C atoms?
Indranil said:In 1 molecule of CO, I have 1 atom of C and 1 atom of O.
so 2 molecules of CO, I have 2 atoms of C and 2 atoms of O.
10 molecules of CO, I have 10 atoms of C and 10 atoms of O. Am I right?
From your context, I have a doubt.
What do you mean by 1 atom of C? Does it mean 1 mol of C atoms?
Could you be more specific on ''one carbon atom and one mole of carbon atoms?'' what is the difference between them? Could you clarify it, please?jedishrfu said:I meant one atom of C or more properly one Carbon (C) atom. Your extension to 1 mole is okay since you're now understanding a mole to be a specific number of carbon atoms
There are no doubts only questions. In american english, doubt means to not believe something is true which can be taken to mean that you think the person is not being truthful.
But since oxygen molecules have two atoms, you get only 5 molecules of oxygen.Indranil said:...

1 atom of C means 1 atom of Avogadro's numbers of C = 1 atom of 6.023 X 10^23 numbers of C atoms?Borek said:1 atom of C is 1 atom of C, 1 mole of atoms of C is 1 mole (6.02×1023) of atoms of C. Typically when we say "1 mole of C" we mean 1 mole of atoms of C.
Merlin3189 said:Right. 1 C + 1 O2 = 2 CO so scale this up to give 10 CO
10C + 5O2 = 10COBorek said:Beware, this is not balanced.
To calculate the moles of oxygen in a CO molecule, you can use the formula:
moles of O = (mass of CO molecule / molar mass of CO) * 1 mole of O / 1 mole of CO
First, determine the mass of the CO molecule by adding the atomic masses of carbon and oxygen. Then, divide this mass by the molar mass of CO, which is 28.01 g/mol. Finally, multiply this value by the ratio of 1 mole of O to 1 mole of CO, which is equal to 1. The resulting value will be the moles of oxygen in the CO molecule.
Knowing the number of moles of oxygen in a CO molecule is important for various chemical calculations and reactions. It allows us to determine the amount of oxygen that will be consumed or produced in a reaction involving CO. It also helps in determining the stoichiometry, or the mole ratio, between CO and other substances in a reaction.
Yes, the number of moles of oxygen in a CO molecule will be different from other molecules that contain oxygen. This is due to the different molecular structures and atomic compositions of different molecules. For example, a molecule of CO2 will have twice the number of moles of oxygen as a molecule of CO.
No, the formula for calculating the moles of oxygen in a CO molecule is specific to this particular molecule. To find the moles of oxygen in other molecules, you will need to use different formulas based on their molecular structures and atomic compositions.
One way to experimentally determine the moles of oxygen in a CO molecule is through gas analysis. This involves measuring the volume of oxygen gas produced when a known mass of CO is reacted with excess oxygen. From the volume of oxygen gas produced, the moles of oxygen can be calculated using the ideal gas law.
