Chapter 1, Problem 7P

Questions 27 to 30: Calculate the mass of each substance from the number of moles given. a 0.769mol lithium chloride b 57.1mol acetic acid, HC2H3O2 c 0.68mol lithium d 0.532mol iron (III) sulfate e 8.26mol sodium acetate acetate ion, C2H3O2

Questions 6-8 refer to a 1.000 g sample of a compound that contains only C, H, and O that undergoes combustion to produce 1.502 g of carbon dioxide and 0.411 g of water vapor.   What is the mass percent of carbon in the sample?  What is the mass percent of oxygen in the sample? The empirical formula (the simplest whole-number combination of atoms in a molecule) of the compound is?

What is the molar mass of acetic acid, in g/mol? Use two decimal places in atomic masses. Only give the numeric value of your answer. Don’t include the units. Respond with the correct number of signficant figures in scientific notation.
