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

Answer»

Solution : `Ca to CaO`
APPLYING POAC for Ca atoms as Ca atomsare conserved,
MOLES of Ca atomsin the reactant
- moles of Ca atoms in the product
= moles of Ca atomsin 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.ofCaO)/(56), wt . of CaO = (56)/(40) = 1.4 g`
