How many grams of `CaO` are required to neutralise `852 g` of `P_4 O_10` ? Draw the structure of `P_4 O_10`.

A

852g

B

1008g

C

85g

D

7095g

Text Solution

Verified by Experts

`6CaO+P_4O_10 to 2Ca_3 (PO_4)_2`
Mole of `P_4O_10` = molar mass of `P_4O_10` = 284g
852g of `P_4O_10=852/284=3` mol
mole of `P_4O_10` reacts with 6 moles of CaCO
3 moles of `P_4O_10` reacts with 18 moles of CaCO
Mass of 18 moles of CaO `=18xx56=1008g`
