I have a problem i don't get...
H3PO4+3NaOH -> 3H2O+Na3PO4
How many moles of Na3PO4 will be produced from 1.7 moles of NaOH in the presence of excess H3PO4?
The equation tells you that 1 mol of Na3PO4 will be produced by 3 mol NaOH (that's one reason you balance the equation). So wouldn't that be 1/3 mol Na3PO4 for each mol NaOH. And you had 1.7 mols? So .....
