Compared to one mole of iron atoms, one mole of oxygen molecules has:?

Question

a) the same number of atoms
b) more atoms
c) less atoms
Please Support answer Thanks

Answer 1

The correct answer is B.

Each oxygen molecule (O2) has two atoms of oxygen, so there are twice as many atoms of oxygen in one mole of oxygen MOLECULES as there are atoms in one mole of irons ATOMS.

Answer 2

I always thought that 1 mole of anything contains Avagodro's number of atoms, so I would think that the answer to your question would be (a) the same number of atoms, and not more atoms. Unless it's a trick question by saying one mole of oxygen "MOLECULES". It should just be 1 mole of iron has the same number of atoms as 1 mole of oxygen.

Answer 3

Compared to one mole of iron atoms, one mole of oxygen molecules have more atoms (answer b).

Reason:
1 mol of iron has 6.022x10^23 atoms.
1 mol of oxygen molecule is 6.023x10^23 molecules in number. Each molecule of oxygen consists of 2 oxygen atoms. So in 1mol oxygen molecules, there are 2x6.023x10^23 oxygen atoms.

Answer 4

less atoms since 1 mole of oxygen molecule has 2 * avagadro Number

Answer 6

A. a million) calculate the moles of Q (employing stoichiometry) 2Fe + 3Q -----> Fe2Q3 a million.000 g Fe / (fifty 5.8452 g/mol) = .01791 mol Fe .01791 mol Fe * (3 mol Q / 2 mol Fe) = .02686 mol Q 2) calculate the grams of Q (employing subtraction) a million.430 g Fe2Q3 - a million.000 g Fe = .430 g Q 3) calculate the molar mass of Q (grams/moles) .430 g Q / .02686 mol Q = 16.0 g/mol Q Q is Oxygen. B. 26 g H2S / (34.0814 g/mol) = .seventy six mol H2S .seventy six mol H2S * (2 mol FeCl3 / 3 mol H2S) = .51 mol FeCl3 .51 mol FeCl3 * (162.2048 g/mol) = 80 2.5 g FeCl3 produced
