how do i do this?

Answer 1

There are 4.184 joules in a calorie. Set up a proportion OR use dimensional analysis.

Answer 3

241 kJ x (1000 J/1 kJ) x (1 calorie/4.184 J) = 5.76 x 10^4 calories. You have the correct answer. Is this a nutrition course? If so, and I notice you wrote Calories and not calories, sometimes the nutritionists call a BIG calorie (a kcal), a Calorie. If you convert to BIG calories, that would be 57.6 kcal = 57.6 Calories = 57.6 big calories.
