How many moles are in 3.01 X 10 to the 23 power of hydrogen?

Answer 1

0.5 moles

One mole of H2 contains 6.02 x 10^23 molecules of H2. To set this up in dimensional analysis form:

[3.01 x 10^23 molecules H2] x [1 mole H2 / 6.02 x 10^23 molecules H2] = ? mole H2

(3.01 x 10^23) / (6.02 x 10^23) = 0.5 mole H2

**Hydrogen is a diatomic gas. When one Hydrogen atom is not combined with another element it will join to another Hydrogen atom to form an H2 molecule.

**One mole of any substance contains 6.02 x 10^23 particles of that substance.

**To give an idea about how large that number truly is:
1) 6.02 x 10^23 inflated basketballs would occupy a volume equal to that of Earth. The pile of basketballs would be as big as the planet.
2) 6.02 x 10^23 eggs would cover the surface of the Earth to a depth of 1 km.
3) If everyone on Earth (6 billion people) were to start counting atoms at a rate of one atom per second for each person it would take 3 million years for all of the atoms in a mole to be counted.

Answer 2

One mole of any substance has 6.02*10^23 molecules (or atoms) of that substance (Avogadro's number). Assuming that the number in your question refers to molecules of hydrogen gas (H2), then that amount contains 0.5 moles (0.5 * 6.02*10^23 = 3.01*10^23).

However, to be accurate, you should specify exactly 3.01*10^23 of WHAT; if, for example, that number refers to H atoms, but the gas is H2, then there are only half that number ( 1.505*10^23) of hydrogen molecules, and it is the molecules that define the moles, and the answer would be 0.25 moles.

Answer 4

that is avogadro's type a million mol is = 6.02x10^23 debris or molecules to get the kind of mols mol = mass divided via molecular weight of the substance which would be derived from the periodic table for occasion in case you elect for to renowned what proportion molecules there are in a 1g of carbon you divide it via is molecular weight the respond would be in mols. multiply mols via 6.02 x 10^23 = sort of molecules interior the substance

Answer 5

half but they could be messing with you and asking how many moles of molecules are in that many atoms then it would be 0.25 moles................... are they messing with you? Maybe you should read the section and then read the question carefully and do a little work on your own.
