Since the combined weight of the 3 pennies was 24 grams before the experiment, and each penny weighed 8 grams after the experiment, this means that the 3 pennies now weigh a total of 24 grams (3 x 8 = 24 grams).
This indicates that the remaining weight of the solution is the original weight of the 3 pennies (24 grams) minus the weight of the pennies after the experiment (24 grams - 8 grams = 16 grams).
Since the salt & vinegar solution had a weight of 16 grams remaining after the experiment, we can conclude that the answer is 16 grams.
Therefore, none of the provided options are correct. However, the closest answer would be 17 grams.
If the pennies weighed 8 grams after the experiment, how much did the salt & vinegar solution weigh?
