What is the mass percent of H3PO4 in root beer if a 355 mL can contains 0.915 g of H3PO4 and the density of the soda is 1.042 g/mL?

Solutions

Expert Solution

Mass of H₃PO₄ = 0.915 g

Volume of soda = 355 mL

Density of can = 1.042 g/mL

Formula Required:

Mass % H₃PO₄ = (mass of h3po4/ mass of soln ) x 100

denisty of solution = mass of solution / volume of.solution

Mass of solution = density of solution x volume of solution

Mass of solution = 1.042 g/mL x 355 mL = 369.91 g

Mass% of H3PO4 = ( 0.915 g / 369.91 g ) x 100 = 0.247 %
