The masses of four objects were measured during a physics experiment. The first and the last each had a mass of 41.918 g. The second and the third objects each had a mass of 24.83 g. Find the total mass of the four objects. Write your answer in scientific notation.
Accepted Solution
A:
For this case, the first thing we must do is add all the masses. We have then: M = (41,918) + (41,918) + (24.83) + (24.83) M = 133,496 We now write the answer in scientific notation: M = 1.33496 * 10 ^ 2 grams Answer: The total mass of the four objects is: M = 1.33496 * 10 ^ 2 grams
