Using the table on the left, calculate the total kilocalories for fats (rounding off the kilocalories to the tens place).
Express the energy to two significant figures and include the appropriate units
Fats(g)- 40,13,10
To calculate the total kilocalories for fats, you need to know the caloric value of fats per gram. Fats have a caloric value of 9 kilocalories per gram.
Total kilocalories for fats = (40g + 13g + 10g) * 9 kilocalories/gram
Total kilocalories for fats = 63g * 9 kilocalories/gram
Total kilocalories for fats = 567 kilocalories
Rounding off to the tens place, the total kilocalories for fats is 570 kilocalories.
To calculate the total kilocalories for fats, we need to use the information provided in the table.
From the table, we can see that the energy content of fats is 9 kilocalories per gram.
Now, we will multiply the number of grams of fats by the energy content of fats.
First, let's calculate the kilocalories for each individual fat:
- For 40 grams of fats: 40 grams * 9 kilocalories/gram = 360 kilocalories
- For 13 grams of fats: 13 grams * 9 kilocalories/gram = 117 kilocalories
- For 10 grams of fats: 10 grams * 9 kilocalories/gram = 90 kilocalories
Now, let's calculate the total kilocalories for fats by summing up the individual totals:
360 kilocalories + 117 kilocalories + 90 kilocalories = 567 kilocalories
Therefore, the total kilocalories for fats (rounded to the tens place) is 570 kilocalories.
