-How many grams of Na3PO4 is actually produced? -Calculate the mass of NaH2PO4 needed to produce this amount of product? -If the molarity of the NaOH solution is 0.5M. How many liters of the NaOH solution is needed?
Sodium phosphate, Naz PO, is used in adults 18 years of age or older to empty the colon (large
intestine, bowel) before a colonoscopy. It is produced by reacting NaH,PO4 and NaOH as shown
on the following balanced chemical equation:
NaH, PO,(s) + 2N@OH(aq) → NazPO4(aq) + 2H2O(1)
In one reaction with a percent yield of 82.5%, 186.50 mL of 0.55 M Na3 PO4 solution is formed.
Molar masses:
Na3PO4
= 163.94 g/mol
NAH2PO4
= 119.976 g/mol
NaOH = 39.997 g/mol
