What amount of CaO will be produced by 1 g of calcium ?

Explanation

`Ca to CaO`
Applying POAC for Ca atoms as Ca atoms are conserved,
moles of Ca atoms in the reactant
- moles of Ca atoms in the product
= moles of Ca atoms in Ca O `= 1 xx` moles of CaO
(`:.` 1 mole of CaO contains 1 mole of Ca atoms )
`("wt. of Ca")/(underset("(Rule 2)")("at. wt. of Ca"))=("wt. of CaO")/(underset(" (Rule 1)")("mol. wt. of CaO"))`
`(1)/(40) = (wt.of CaO)/(56) , wt . of CaO = (56)/(40) = 1.4 g`
