Express the energy to two significant figures and include the appropriate units.

Thanks

Answer 1

Answer : As per the given informations in the question . the first thing is to be noted that 3.87 Calories per Gram of glucose. Hence here we need to calculate the total mass of glucose

we know that 100 ml contain = 5.9 g Glucose

3200 ml contains = 5.9 * 3200 / 100 = 188.8 gram of glucose

Now we know that , 1 g glucose contains = 3.87 calories

then , 188.8 g contains = 3.87 * 188.8 calories = 730.656 calories

= 0.73 KCalories

Hence the required answer is 0.73 KCalories . thank you
