Question

The USDA suggests that a person should limit the amount of added sugar he or she consumes to 10 teaspoons per day on a 2000-calorie diet. How many grams of sugar are there in 10 teaspoons?

A) 40 grams
B) 50 grams
C) 60 grams
D) 70 grams

Answer 1

To determine the amount of sugar in 10 teaspoons, one can multiply the calorie content per teaspoon of sucrose by the number of teaspoons and then divide by the calories per gram of carbohydrates. The calculation results in approximately 40 grams of sugar, which corresponds to Option A.

Step-by-step explanation:

The amount of sugar in 10 teaspoons can be calculated using the calorie content per teaspoon and the average number of calories per gram of sucrose. Since one teaspoon of sucrose contains 16 Calories, and carbohydrates (including sugar) average 4.1 Calories per gram, dividing the total calories by the calories per gram gives us the mass in grams.

To find the mass of sugar in 10 teaspoons:

1. Calculate the total calories: 16 Calories/teaspoon × 10 teaspoons = 160 Calories.
2. Divide the total calories by the number of calories per gram: 160 Calories / 4.1 Calories/gram ≈ 39 grams.

Therefore, the correct answer to the question is approximately 40 grams (Option A).
