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

A

958 g

B

1008 g

C

1032 g

D

993.9 g

Text Solution

Verified by Experts

The correct Answer is:
B
`6CaO+P_(4)O_(10)rarr2Ca_(3)(PO_(4))_(2)`
`""^(n)P_(4)O_(10)=("wt in gm")/("G.M. wt")=(852)/(284)="3 moles"`
`therefore" 18 moles of CaO is equired "`
`"wt of CaO required "=18xx56`
`="1008 gms"`
