I know how to calculate for the pH and molar concentration, but I don't know what to do with the 7.0 mass % solution with density of 1.0353g/mL
OpenStudy (anonymous):
hmmmmm, im guessing you do 1.0353 x .07 to find the g of H3PO4

OpenStudy (anonymous):
i'll just assume theres 100g so theres 7 g of H3PO4, then i find the mol of H3PO4. Also D= m/V so i can find V by doing m/D. then i can do mol/L to find Concentration
OpenStudy (cuanchi):
Yes that's is correct!!
