Mass of calcium hydroxide is formed when 10g of calcium oxide reacts with 10g of water is 13.024 gram
Mass is a measure of the amount of matter in a substance or an object.
Here given data is
Calcium oxide = 10g
Water = 10g
We have to calculate mass of calcium hydroxide = ?
The reaction is
CaO + H₂O → Ca(OH)₂
1 mole of CaO reacted with 1 mole of H₂O to form 1 mole of Ca(OH)₂
Moles = mass/molar mass
Mole of CaO = 10g/56g/mol = 0.179 mole
Mole of H₂O = 10g/18g/mol = 0.556 mole
CaO is the limiting reagent therefore by using of mole ratio of CaO : Ca(OH)₂ is 1 : 1 mole of Ca(OH)₂ = 0.179 mole
Mass = mole × molar mass
Mass = 0.176 × 74g/mol
Mass = 13.024 gram
