2016 g

1008g

504 g

1800g

Text Solution

Verified by Experts

The correct Answer is:

`underset ("base") (6 Ca O _(4)) + underset("acid") ( P _(4) O _(10)) to underset("sak")( 3 Ca _(3) (PO _(4)) _(2))`
Mole ratio of reactuant `= ( Ca O )/( P _(4) O _(10)) = (6)/(1)`
Molar mass of `P _(4) O _(10) = 284`
`therefore` Mass of CaO required `= (6 xx 852)/(284) xx 56 = 1008 g`
