0.835moles
Explanation:
Given parameters:
Number of moles of H₂ = 1.67moles
Unknown:
Number of moles of O₂ that reacted completely = ?
Solution:
The number of moles is a quantity used in chemistry to express the amount of matter contained in a substance.
It is synonymous to using units like dozen, gross for quantifying goods.
In 1 mole of a substance, we have 6.02 x 10²³particles
Equation of the reaction:
2H₂ + O₂ → 2H₂O
The equation is balanced;
2 moles of H₂ hydrogen gas reacted with 1 mole of O₂ oxygen gas;
1.67 mole of H₂ gas will react with: = 0.835moles
The number of moles of O₂ that completely reacted was 0.835moles.
