Calculate the boiling point of a solution prepared by dissolving 70.0 g of naphthalene, c10h8 (a nonvolatile nonelectrolyte), in 220.0 g of benzene, c6h6. the kb for benzene = 2.53oc/m. the boiling point of pure benzene is 80.1oc.. ans: 86.4 degrees celsius. i did this so far. 1)70g c10h8(1mol c10h8/128gc10h8)= .546mol c10h8. benzene)=2.482m. 3) (2.482)(2.53 c/m)=6.289. i'm not sure if i am starting this off right, can anyone me get the correct answer? ans ty!

Which statement describes the appearance of a temperature-vs.-time graph? a horizontal line shows that the temperature increases at a constant rate over time. a vertical line shows that the temperature decreases at a constant rate over time. horizontal lines where the temperature is constant during phase changes connect upward-sloping lines where the temperature increases. horizontal lines where the temperature increases are connected by upward-sloping lines where the temperature is constant for each phase.
