Homework Help: chem 103

Posted by Andrew on Sunday, July 14, 2013 at 1:35pm.

Still stuck on this question. How many grams of Na3PO4 would you need to make 0.225L of 8.0M stock solution? 8.0 M of NaPo multiplied by .225L NaPO = 1.8 mols of Na3PO4. Then multiply the 1.8 mol times the mass of Na3PO4 which is 163.93 grams?, yes? This would make 295.07 grams of Na3PO4, yes? thank you!!
