Question
how many grams of NaOh are needed to make 50 g of Na3PO4 according to the equation: 3NaOH+H3PO4=Na3PO4+3H2O
(i'm not sure where to even start for this!)

The procedure for working stoichiometry problems.
1. Write and balance the equation. You have that.
2. Convert whatinformation you have (you want 50 g Na3PO4) into mols. mols = grams/molar mass = ?
3. Using the coefficients in the balanced equation, convert mols Na3PO4 to mols NaOH. That's
?mols Na3PO4 x (3 mols NaOH/1 mol Na3PO4) = ?
4. Now convert mols NaOH to grams. g = mols x molar mass = ?
