Answer 1

Answer #1

In given balanced reaction,

3 Moles of calcium are reacted with 2 Moles of phosphoric acid.

Therefore for 1.372 Moles of calcium required

= (1.372 Mole Ca x 2 Mole H2PO4)/3mole Ca

= 2.744 / 3

= 0.914 Moles of phosphoric acid.

Therefore, for complete reaction of 1.372 Moles of calcium metal require 0.914 Moles of phosphoric acid.
