Question

Define mole. Write two applications of mole in chemical calculations.

Answer 1

Thanks for the question

The mole is determined as the amount of substance comprising the same number of chemical units (atoms, molecules, ions, electrons, or other designated actualities or groups of entities) as precisely 12 grams of carbon-12

The ratios of moles of substances associated in any balanced chemical reaction are identical to the ratios of moles in any multiple or submultiple of the balanced chemical reaction.

→ $CO(g) +0.5O_2(g) =>CO_2(g)$

→$2CO(g) + O_2(g) => 2CO_2(g)$

Thank You

Answer 2

_______Mole(mol.)
Def:
In chemistry, 1 mole is that quantity of particles as there atoms in 12 grams of the cabon-12 isotope, ie
6, 023 × 10 ^23 particles which is the Avogadro number which makes up 1 mole of a substance.

eg 1)
2 H2+ O2 → 2 H2 O

We interpret this as “two molecules of hydrogen react with one molecule of oxygen to make two molecules of water.” The chemical equation is balanced as long as the coefficients are in the ratio 2:1:2.

eg 2)
P4 + 5 O2 → P4 O10

The coefficients represent the number of moles that react, not just molecules. We would speak of this equation as “one mole of molecular phosphorus reacts with five moles of elemental oxygen to make one mole of tetraphosphorus decoxide.”

hope it helps
