How many grams of CaO are required to neutralise 852g of `P_(4)O_(10)`?

Text Solution

Verified by Experts

The reaction will be:
`6CaO+P_(4)O_(10)rarr2Ca_(3)(PO_(4))_(2)`
`852g P_(4)O_(10) m3 "mol" P_(4)O_(10)`
1 mole of `P_(4)O_(10)` neutralises 6 moles of `CaO`
`therefore 3 "moles of" P_(4)O_(10)` will neutralise 18 moles of CaO.
`therefore "mass of" CaO=18xx56=1008g`
