Moles of Sulfuric acid- Hâ‚‚SOâ‚„ needed to react completely : 3.2 moles

Further explanation

A reaction coefficient is a number in the chemical formula of a substance involved in the reaction equation. The reaction coefficient is useful for equalizing reagents and products.

Reaction(balanced)

2LiOH + H₂SO₄ → Li₂SO₄ + 2H₂O

From the reaction equation above, the reaction coefficient shows the mole ratio of reagents and products

moles of Lithium hydroxide-LiOH = 6.4 moles

mol ratio of LiOH : Hâ‚‚SOâ‚„ = 2 : 1, so mol Hâ‚‚SOâ‚„ :

[tex]\tt moles~H_2SO_4=\dfrac{1}{2}\times 6.4=3.2[/tex]
