Eric has a two rocks samples. One has a mass of 600 grams and the other has a mass of 1 kilogram. He recorded the total mass as 7 kilogrmaas. Explain what he did wrong? What should be the correct answer in grams?
1 kilogram = 1000 grams
so we have 1000 + 600 = 1,600 grams
or
1.6 kilograms
Eric made a mistake when he recorded the total mass as 7 kilograms. The mistake he made was likely in adding the masses of the two rock samples together without converting them to the same unit.
To find the correct answer, we need to convert the mass of the samples to the same unit, either grams or kilograms. In this case, let's convert them all to kilograms.
The first rock sample has a mass of 600 grams. To convert grams to kilograms, we divide by 1000 since 1 kilogram is equal to 1000 grams. So, 600 grams is equal to 600/1000 = 0.6 kilograms.
The second rock sample has a mass of 1 kilogram, which is already in kilograms.
Now, let's add the masses correctly. The total mass in kilograms would be 0.6 kilograms + 1 kilogram = 1.6 kilograms.
To convert the correct answer back to grams, we multiply the total mass in kilograms by 1000 since 1 kilogram is equal to 1000 grams. Therefore, the correct answer in grams would be 1.6 kilograms * 1000 = 1600 grams.
So, Eric's mistake was that he added the masses of the rock samples without converting them to the same unit, and the correct answer for the total mass should be 1600 grams.
