The answer is: 4) " 2.7 * 10⁵ mg " . ________________________________________________________ Explanation: ________________________________________________________ Since all answer choices given are in "mg" ("milligrams"); we need to convert our given value, "0.27 kg" ("kilograms") to "mg" ("milligrams"). ________________________________________________________ Note the following "exact value" conversions: ________________________________________________________ 1000 mg = 1 g ; 1000 g = 1 kg.
(0.27 kg) (1000 g / 1 kg) (1000 mg/1 g) = __?__ mg ; _____________________________________________________ The units of "kg", and "g" cancel to "1" and we are left with: ________________________________________________ 0.27 * 1000 * 1000 mg = 270,000 mg = 2.7 * 10<span>⁵ </span> mg ; which is: _______________________________________________________ → Answer choice: # 4 . _______________________________________________________
