Step 2
Calculate the difference in the mass of protein contained in 200 g of minced beef compared with 200 g of mycoprotein mince.
Answer
To calculate the protein difference:
-
Find the protein in 200 g of minced beef:
- Protein per 100 g of minced beef = 20.0 g
- Protein in 200 g = 20.0 g × 2 = 40.0 g
-
Find the protein in 200 g of mycoprotein mince:
- Protein per 100 g of mycoprotein mince = 13.5 g
- Protein in 200 g = 13.5 g × 2 = 27.0 g
-
Calculate the difference:
- Difference = Protein in minced beef - Protein in mycoprotein mince
- Difference = 40.0 g - 27.0 g = 13.0 g
Thus, the difference in the mass of protein is 13.0 g.
