How many grams of nitrogen are contained in 2500 kcal diet that provides 15 percent of the energy as protein?
To calculate the amount of nitrogen in a diet, you typically assume that 16% of protein is nitrogen. In this case, if 15% of the energy in the diet comes from protein, you can calculate the total protein in the diet (2500 kcal * 0.15 = 375 kcal from protein). Then, convert this to grams of protein using the fact that protein provides 4 kcal/g. Finally, since protein is about 16% nitrogen, you can calculate the total grams of nitrogen in the diet.
How long need to exercise to expend 100 kcal while expending the energy rate of 270 W?
To calculate how long you need to exercise to expend 100 kcal at an energy rate of 270 W, first convert 100 kcal to Joules (1 calorie = 4.184 J), then divide the energy in Joules by the power in Watts to find the time in seconds. Finally, convert the time from seconds to minutes. In this case, you would need to exercise for approximately 44.3 seconds to expend 100 kcal at an energy rate of 270 W.
How to calculate calories in chemistry?
To calculate calories in chemistry, you can use the formula: Calories mass x specific heat capacity x temperature change. This formula helps determine the amount of energy required to raise the temperature of a substance. By measuring the mass of the substance, its specific heat capacity, and the temperature change, you can calculate the calories.
What represents the greatest amount of energy 1000 cal 500 Cal 100 kcal or 100000 J?
100000 J represents the greatest amount of energy compared to 1000 cal, 500 Cal, and 100 kcal. 1 Cal = 1000 cal = 1 kcal = 4184 J. Therefore, 100000 J is equivalent to about 23.9 kcal.
How many kilo calories kcal are there in 1 mole of ATP?
There are approximately 7.3 kilocalories (kcal) of energy in 1 mole of ATP.
What is the percent of kcal from 1 grams of fat?
One gram of fat provides approximately 9 kilocalories (kcal). To find the percentage of kcal from 1 gram of fat relative to a typical daily intake (for example, 2,000 kcal), you would calculate (9 kcal / 2000 kcal) × 100, which equals about 0.45%. Therefore, 1 gram of fat contributes about 0.45% of a 2,000 kcal daily intake.
How do you calculate k cal per cup of dog food?
To calculate kilocalories (kcal) per cup of dog food, first check the food's packaging for its calorie content, usually expressed as kcal per kilogram (kg) or kcal per 100 grams. If the calorie content is given per kg, divide that number by 4.54 (the number of kg in a pound) to get kcal per pound. Then, determine the weight of one cup of the dog food in pounds (or grams) and multiply that weight by the kcal per pound (or kcal per gram) to find the total kcal per cup.
How many kcal of energy does the cheeseburger contain if it has 19 grams of fat 20 grams of carbohydrate and 28 grams of protein?
To calculate the total kcal in the cheeseburger, you can use the caloric values of macronutrients: fat provides 9 kcal per gram, carbohydrates provide 4 kcal per gram, and protein provides 4 kcal per gram. Calculating each component: Fat: 19 g × 9 kcal/g = 171 kcal Carbohydrates: 20 g × 4 kcal/g = 80 kcal Protein: 28 g × 4 kcal/g = 112 kcal Adding these together gives: 171 + 80 + 112 = 363 kcal. Thus, the cheeseburger contains approximately 363 kcal of energy.

What is the kcalorie value of a meal supplying 90g of carbohydrates 30 g of protein 30 g of fat and 5 g of alcohol?
To calculate the kcalorie value of the meal, you can use the following values: carbohydrates provide 4 kcal/g, protein provides 4 kcal/g, fat provides 9 kcal/g, and alcohol provides 7 kcal/g. For the meal: Carbohydrates: 90g × 4 = 360 kcal Protein: 30g × 4 = 120 kcal Fat: 30g × 9 = 270 kcal Alcohol: 5g × 7 = 35 kcal Adding these together: 360 + 120 + 270 + 35 = 785 kcal. Thus, the total kcalorie value of the meal is 785 kcal.
What is the kilo calorie value of a meal supplying 100 gram. carbohydrates 25 gram. protein and 10 p fat?
To calculate the kilocalorie value of the meal, you can use the following approximate values: carbohydrates provide 4 kcal per gram, protein provides 4 kcal per gram, and fat provides 9 kcal per gram. Therefore, for the meal: Carbohydrates: 100 g x 4 kcal/g = 400 kcal Protein: 25 g x 4 kcal/g = 100 kcal Fat: 10 g x 9 kcal/g = 90 kcal Adding these together gives a total of 400 + 100 + 90 = 590 kcal for the meal.
How do you calculate only turbine efficiency not turbine cycle efficiency?

How many kilocalories of heat would be needed to melt 0.12kg of ice at 0 degrees c and increase the temperature to 25 degrees c?
To calculate the total kilocalories needed, first, you need to melt the ice. The latent heat of fusion for ice is approximately 80 kcal/kg, so melting 0.12 kg of ice requires 0.12 kg × 80 kcal/kg = 9.6 kcal. After melting, you need to raise the temperature of the resulting water from 0°C to 25°C. The specific heat of water is about 1 kcal/kg°C, so heating 0.12 kg of water by 25°C requires 0.12 kg × 25 kcal/kg°C = 3 kcal. Therefore, the total heat needed is 9.6 kcal + 3 kcal = 12.6 kcal.
If a woman consumes 2200 total kcal per day and 30 percent of the kcal come from fat What is the number of grams of fat the woman consumes?
Fat = 9 kcal 2,200 kcal x 0.30 kcal = 660 kcal 660 / 9 kcal = 73.33 g = 73 g of fat per day
If one slice of chocolate cake contains 35g of carbohydrates 15g of fat and 5g of protein calculate the kilo-calories that each slice of cake contains?
