- Using the Kf value for water from your book, you prepare a solution at 25.0 °C from 9.17 molof some solid and 7.31 L of water (d = 0.997 g/mL), but you forgot the identity of the solid. Youknow it was either glucose, sodium acetate, sodium phosphate, or sodium sulfate. You decideto determine the mass indirectly by measuring the freezing point depression of the solution,and find that the solution has a freezing point of −7.02 °C. Which substance is it and how doyou know this?arrow_forwardWhat is the symbolic expression for the equillibrium constant for the reaction: 2C2H6(g) + 7 O2(g) = 4CO2(g)+6H2O(g)?arrow_forwardCalculate the Kc for 2NO(g) + Br2(g) ⇌ 2NOBR(g) with Kp=2.4 at 373 K.
