you are asked to determine how many moles of water you can produce from 4.0 mol of hydrogen and excess oxygen. (excess oxygen means that so much oxygen is available it will not run out.) which of the numbers that appear in the balanced chemical equation below are used to perform this calculation?

We used both the hydrogen and water coefficients from the aforesaid solution (mole ratio).

Chemical Reaction

[tex]2H_{2}[/tex] + [tex]O_{2}[/tex]  → [tex]2H_{2}O (Balanced)[/tex]  

Assuming moles of hydrogen are the limiting reactant, calculate the moles of water

[tex]moles H_{2}O = (4 moles H_{2} ) \frac{2moles H_{2}O }{2moles H_{2} } = 4 moles H_{2}O[/tex]

What is Moles?

A substance's mass, which is made up of the same number of essential components, is measured in moles. A 12 gram example has atoms that are the same as 12C. The basic building blocks of a substance could be molecules, atoms, or formula units.

The quantity of chemical elements is indicated by the mole fraction. One mole of any substance has a value of 6.023 x 1023. (Avogadro number). The byproducts of the chemical reaction can be measured using it. The unit is denoted by the sign mol.

The following expression represents the number of moles formula

Number of moles = Mass of substance / Mass of one mole .
