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!

Nebulae are enormous clouds in outer space. they are made mostly of hydrogen gas, helium gas, and dust. some nebulae glow brightly, while others do not. the stars that people see are huge, bright balls of glowing gas. they are made mostly of hydrogen and helium. which statement correctly describes other ways in which nebulae and stars are different? a. stars can form inside a nebula but a nebula can never be produced by any star. b. a star always has a higher density than a nebula. c. stars can never form inside a nebula but a nebula can be produced by any star. d. a nebula always has a higher density than a star.
