In a candy factory, nutty chocolate bars contain 22.0% by mass pecans. If 4.8kg of pecans were used for candy last Tuesday, how many pounds of nutty chocolate bars were made?

If 4.8 kg of pecans were used, that means that of the total nuttly chocalate bars (in kg) made that day, 22.0% of it is equal to 4.8 kg. Mathematically that means, 22.0% x chocalate bars = 4.8 0.22 x chocolate bars = 4.8 Working backwards, we have chocolate bars = 4.8/0.22 = 21.82 kg Hence, the weight of the chocolate bars amade is equal to 21.82 kg. Since we need the weight in pounds, we must take note that 1 kg = 2.2 lbs. So, we have 21.82 kg = 21.82 (2.2) = 48.00 pounds Answer: 48.00 pounds
