1)a reaction between calcium and a solution of 1.2moldm-3 phosphoric acid produced 3 mol of H2 gas.
a) Minimum volume of phosphoric acid would have been needed for reaction: I got 1.6cm3
b)Mass of calcium added tpo this acid? I got 120.3
c)Maximum amount of calcium phosphate that could be obtained by thi sprocess???

Forgot to post the other question for thisequation:
2)
2.00g of calcium was added to 500cm3 of 0.1moldm-3 and the solution was left until all the effervescence had stopped.
a) What volume of 2 moldm-3 NaOH solution would be needed to neutralise th remaining H3PO4?

PLease help showing all working out

does effervescence affect the calculations?
