Problem
The following masses are given in kilograms. Use metric prefixes on the gram to rewrite them so the numerical value is bigger than one but less than 1000. For example, 7×10−4 kg could be written as 70 cg or 700 mg. (a) 3.8×10−5 kg; (b) 2.3×1017 kg; (c) 2.4×10−11 kg; (d) 8×1015 kg; (e) 4.2×10−3 kg.
