Floyd's Chemistry Lab Manual Instructs Him to Weigh Out 20

Short Answer

Floyd's chemistry lab manual instructs him to weigh out 20 grams of sodium carbonate. Floyd remembers that his sample's mass differed from the 20-gram target amount by 0.36 grams, but does not recall whether he weighed out more or less than the requested amount. Use an absolute value equation to find the possible values for Floyd's sample.
