Question

When boiling​ water, a hot plate takes an average of 9 minutes​ [min] and 26 seconds​ [s] to boil 110 milliliters​ [mL] of water. Assume the temperature in the lab is 74 degrees Fahrenheit ​[Superscript o Baseline Upper F​]. The hot plate is rated to provide 278 watts​ [W]. If we wish to boil 110 milliliters​ [mL] of acetone using this same hot​ plate, how long do we expect the process to​ take? Acetone has a boiling point of 56 degrees Celsius ​[Superscript o Baseline Upper C​]. ​[Hint: you must determine the efficiency of the​ hotplate.]
