How many moles of water does 6.02 x10 23 molecules represent?
1 mole of any substance has 6.02 x 1023 molecules. So, in our case we have 1 mole of water.
How many molecules are in 6.02 moles of water?
A mole (mol) is the amount of a substance that contains 6.02 × 10 23 representative particles of that substance. The mole is the SI unit for amount of a substance. Just like the dozen and the gross, it is a name that stands for a number. There are therefore 6.02 × 10 23 water molecules in a mole of water molecules.
How many moles of H2O does 1.2 x10 24 molecules represent?
1 mole of any substance has 6.02 x 1023 molecules. For getting thenumber of moles we can divide 1.2 x 1024/6.02 x 1023 and we receive 2 moles.
How many moles is 3.52 x10 24 molecules of water?
A chemical formula that shows the number and kinds of atoms in a molecule (not the arrangement of the atoms.) Moles in (3.52 X 10^24) molecules of water. 3.52 x 10^24 molecules x `1mol/6.02 x 10^23 molecules = 5.85 moles of H2O.
Why is it 6.02 x10 23?
Just as an amount of 12 is described by the term dozen, Avogadro’s number is described by the term mole. A dozen eggs is 12 eggs; a mole of atoms is 6.02 X 1023 atoms. … Thus, one mole of an element has a mass in grams equal to the atomic weight of that element and contains 6.02 X 1023 atoms of the element.
How many molecules is 2.0 moles?
Thus, if we have 1 mole of a molecule present, we have 6.022*10^23 of those molecules present. If we have 2 moles of a molecule present, we have 2*1.022*10^23 of that molecule present etc.
How do you find moles in molecules?
Converting between molecules and moles is done by either multiplying by or dividing by Avogadro’s number:
- To go from moles to molecules, multiply the number of moles by 6.02 x 1023.
- To go from molecules to moles, divide the numbers of molecules by 6.02 x 1023.
How many water molecules are in 2 mole of water?
Since one mole is defined as 6.022 x 10^23, and there are two hydrogen per molecule, that would mean that there are exactly 12.044 x 10^23 molecules of hydrogen in one mole of water. Double that for 2 moles, and there are 24.088 x 10^23 hydrogen atoms in one mole of water.
How many molecules of water are there one mole of H2O?
6.022 x 1023 water molecules represent one mole of water.
