Calculate the molarity and molality of a solution that is 18.0% by mass phosphoric acid (H_3PO_4) and that has a density of 1.155 g/mL.
Calculate the mole fraction of phosphoric acid (H3PO4) in a 25.4% (by mass) aqueous solution. (Assume 750 mL of solution.) What is the molarity of the solution? What is the molality? (At 20 ° C, the density of phosphoric acid is 1.1462 g/mL and the density of water is 0.99823 g/mL.)
376.0 g of phosphoric acid, H3PO4, are dissolved in 2.5×103 g of water, H2O. What is the molality (m) of phosphoric acid? your answer should include two significant figures. Provide your answer below:
An aqueous solution of phosphoric acid, that is 0.500 percent by weight phosphoric acid, has a density of 1.0010 g/mL. A student determines that the freezing point of this solution is -0.129 °C. Based on the observed freezing point, what is the percent ionization of the acid and the value of Ka1? Assume that only the first ionization of the acid is important. Kf for H2O is 1.86 °C/m. % ionized = % Ka1 =
