Atlantic herring (raw): - 100 g has 158 kcal - 1 fillet (184 g) has 291 kcal Pacific herring (raw): - 100 g has 195 kcal - 1 fillet (184 g) has 359 kcal.
1 kcal = 1000 cal. 1 cal = 4.18 J
How many kcal are produced when 32.0g of CH4 react? CH4+2O2->CO2+2H2O+218 kcal
The difference between kcal and cal is 1000 cal = 1 kcal. However, we usually count food calories with kcal, and use kcal and cal interchangeably. Therefore, 9 kcal [Food Calories] = 9 cal. So, to the point: If there are 9 kcal in 1 g of fat, there are 9000 kcal in 1 kg of fat (1 kg = 1000 g).
Fat = 9 kcal 2,200 kcal x 0.30 kcal = 660 kcal 660 / 9 kcal = 73.33 g = 73 g of fat per day
9 kcal/g
Approx. 86 kcal/100 g.
Simply - your recommended daily caloric intake consists of three types of so called macronutrients: Carbohydrates, found in bread, rice, paste, ... - at 4 kcal/g Protein, found in fish, beef, poultry, eggs - at 4 kcal/g Fats, found in Oil, Meat, butter - at 9 kcal/g so if your recommended intake ist 2000 kcal/day and 50g of fats you could eat like this: 50 g fats * 9 = 450 kcal 150 g protein * 4 = 600 kcal 250 g carbs *4 = 1000 kcal ------------------------------------ approx. 2000kcal of course if you eat less protein and more fat (typical western diet) you could have this: 100 g fats * 9 = 900 kcal 50 g protein * 4 = 200 kcal 200 g carbs *4 = 800 kcal ------------------------------------ approx. 1900kcal So you BELOW recommend kcal but ABOVE recommend fat intake. Hope this helps.
100 g of dried spaghetti has about 384 kcal which is 1456 kilojoules.
Assuming 4 kcal/g for carb and protein and 9 kcal/g for fats, the total would be (15 x 9) + (25 x 4) + (20 x 4) = 315 kcal.
g KNO3 = MW KNO3 g/mole * (107kJ / 4.186 kJ/kcal) / (-dHsolv kcal/mole) -dHsolv= -155.5+1638 kcal/mole It equals to 311 g of KNO3 Convert to Kg by /1000!
The atomic mass of potassium is 39.10 g/mol. 1.90 mol K * (39.10 g K / 1 mol K) = 74.3 g K
