To calculate the total kilocalories for proteins, we need to use the information provided in the table, which is the amount of proteins in grams.
First, we need to convert the given grams of proteins to kilocalories.
The conversion factor for proteins is that 1 gram of protein provides approximately 4 kilocalories of energy.
So, let's calculate the total kilocalories:
47 grams of proteins * 4 kilocalories/gram = 188 kilocalories
4 grams of proteins * 4 kilocalories/gram = 16 kilocalories
10 grams of proteins * 4 kilocalories/gram = 40 kilocalories
Adding all these values together, we get:
188 kilocalories + 16 kilocalories + 40 kilocalories = 244 kilocalories
Therefore, the total kilocalories for proteins is 244 kilocalories, rounded to the tens place.
Using the table on the left, calculate the total kilocalories for proteins (rounding off the kilocalories to the tens place).
Express the energy to two significant figures and include the appropriate units
Proteins(g)- 47,4,10
