Does 1 mole of hydrogen atoms equals 1 mole of helium atoms?
Yes. In either case they will be 6.02*10^23.
How can a mole of any substance contain the same number of particles?
That's just the way it was set up. 6.022x1023 atoms of an element equals one mole of that element. 6.022x1023 molecules of a compound equals one mole of that compound. Remember, a mole does not measure weight. One mole of hydrogen weighs a lot less than a mole of acetic acid. A mole just means 6.022x1023 particles, whether those particles are atoms, ions, molecules, or ionic compounds.
What is the mole fraction of oxygen in a gas mixture that is 37 percent oxygen and 63 percent nitrogen in volume?
the mole fraction of oxygen= 37/100 0.37 the mole fraction of Nitrogen= .63 that equals to give 1
What is the unit of mole fraction?
Mole fraction is dimensionless. It's the amount of moles of species "A" divided by the total amount of moles in the mixture. So "mole A / mole total" equals "dimensionless". To add clarity in the use of mole fractions, one could add as "unit" mole A / mole "mixture".
What is the mole fraction of each component if 3.9g of benzene is dissolved in 4.6g of toluene?
The molar mass of benzene (C6H6) is 78.11 grams per mole. The molar mass of toluene is 92.14 grams per mole. Mole fraction of a solute equals moles of solute divided by the moles of solute plus the moles of solvent. .5 of each is the mole fraction.
1 mole equals how many l?
One mole is Avogadro's number of anything. If you had a mole of donuts, you'd have 6.02 x1023 donuts.
How many CO2 moles comprise one mole of CO2?
6.02 ten to the power of 23
What does one mole of a substance represent on a microscopic atomic basis?
One mole is what 6.022x1023 molecules of an element masses. Example: One mole of Carbon equals 12.01 grams.
Does 1 mole of hydrogen atoms equals 1 mole of helium atoms?
Yes. In either case they will be 6.02*10^23.
What is the mass of a half a mole of CO2?
1 mole CO2 has about 44 grams, so half a mole of CO2 equals 22 grams
How can a mole of any substance contain the same number of particles?

Avogadros number of representative particals is equal to one?
Avogadro's number of any particles or countable objects, equals by definition 1 (exact) mole.
How many molecules of H2O equals 1 mole of H2O?
the rule for solving amount of molecules is N(molecules)=6x10^23 x n(amount of mole) therefore there are 6x10^23 molecules in 1 mole of anything or in this case of H20

The molar mass of benzene (C6H6) is 78.11 grams per mole. The molar mass of toluene is 92.14 grams per mole. Mole fraction of a solute equals moles of solute divided by the moles of solute plus the moles of solvent. .5 of each is the mole fraction.
1 nano mole equals how many micro mole?
nano is a prefix that means 10-9, so a nanometere is 10-9 of a meter. So a nanomole will be 10-9 of a mole. so a mole is 109 nanomoles.
