The grams of protein in 1 cup of soup that has 110 Cal{\rm Cal} with 7 g{\rm g} of fat and 9 g{\rm g} of carbohydrate.
Express your answer using one significant figure.
Assuming Cal = 4 for protein, 4 for carbohydrates and 9 for fat, then
110 Cal-(7*9)-(9*4)-(4x)
And your question would make more sense without the {\rm g} mishmash.
To find the grams of protein in 1 cup of soup, we need to subtract the calories from fat and carbohydrates from the total calories and then convert the remaining calories to grams of protein.
Step 1: Calculate the calories from fat and carbohydrates:
- Fat calories: Since 1 gram of fat contains 9 calories, we can calculate the calories from fat by multiplying the grams of fat by 9: 7 g * 9 cal/g = 63 cal.
- Carbohydrate calories: Similarly, 1 gram of carbohydrates contains 4 calories. Thus, we multiply the grams of carbohydrates by 4: 9 g * 4 cal/g = 36 cal.
Step 2: Subtract the calories from fat and carbohydrates from the total calories:
110 cal - (63 cal + 36 cal) = 11 cal.
Step 3: Convert the remaining calories to grams of protein:
Since 1 gram of protein contains 4 calories, we can convert the remaining calories to grams of protein by dividing by 4: 11 cal / 4 cal/g = 2.75 g.
Using one significant figure, the grams of protein in 1 cup of soup would be 3 g.
