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
Protein(g)- 47,4,10
To calculate the total kilocalories for proteins, we will use the following formula:
Total kilocalories for proteins = Protein(g) * 4 kilocalories/g
Given that the protein intake is 47.4g, we can substitute this value into the formula:
Total kilocalories for proteins = 47.4g * 4 kilocalories/g
Total kilocalories for proteins = 189.6 kilocalories
Therefore, the total kilocalories for proteins is 190 kilocalories (rounded to the tens place)
To calculate the total kilocalories for proteins, we need to use the information provided in the table on the left.
From the table:
Protein (g) = 47, 4, 10
We need to find the energy content of these proteins. According to the table, proteins have 4 kilocalories per gram.
To calculate the total kilocalories for proteins, we multiply the protein (g) value by the energy content per gram:
Total kilocalories for proteins = Protein (g) x Energy content per gram
For the given values:
Total kilocalories for proteins = (47 x 4) + (4 x 4) + (10 x 4)
Calculating further:
Total kilocalories for proteins = 188 + 16 + 40
Total kilocalories for proteins = 244 kilocalories
Therefore, the total kilocalories for proteins is 244 kilocalories (to two significant figures).
