Carbon tetrachloride, ccl4, was once used as a dry-cleaning solvent, but is no longer used because it is carcinogenic. at 57.8 °c, the vapor pressure of ccl4 is 54.0 kpa, and its enthalpy of vaporization is 33.05 kj/mol. use this information to estimate the normal boiling point for ccl4.

Scientists often have to deal with numbers that are either very large or very small. for example, the radius of the sun is approximately 696,000 kilometers, while bacterial cells are as small as 1.9 × 10-4 millimeters. express each number in an alternate form.
