We are asked to estimate the number of grams of carbohydrate and fat in the celery.
Total fuel value = 9.0 kcal
Fat provides = 1.0 kcal
very little protein → 0 kcal (assume negligible)
Carbohydrate provides = Total - (Fat + protein)
= 9.0 - 1.0 = 8.0 kcal
A stalk of celery has a caloric content (fuel value) of 9.0 kcal. If 1.0 kcal is provided by fat and there is very little protein, estimate the number of grams of carbohydrate and fat in the celery.
