Eli broke a cell sample into 14 batches, each weighing 4.7 x 10^-8 grams. How much did the original sample weigh? Use scientific notation to express your answer.

1 answer

To find the weight of the original sample, we need to multiply the weight of each batch by the number of batches.

Weight of each batch = 4.7 x 10^-8 grams
Number of batches = 14

Total weight = (4.7 x 10^-8 grams) x 14 = 65.8 x 10^-8 grams

Now, we can simplify the total weight in scientific notation:

65.8 x 10^-8 grams = 6.58 x 10^-7 grams

Therefore, the original sample weighed 6.58 x 10^-7 grams.
