How much heat is absorbed by 1.0 g of iron when its heated to 15 degrees celsius?
The specific heat capacity of iron is 0.449 J/g°C. To calculate the heat absorbed, use the formula Q = mcΔT, where Q is the heat absorbed, m is the mass in grams, c is the specific heat capacity, and ΔT is the temperature change. Plugging in the values, the heat absorbed by 1.0 g of iron heated to 15°C is 6.735 J.
How much heat is absorbed by 60.0 grams of copper when it is heated from 293 Kelvin to 353 kelvin?
The specific heat capacity of copper is 0.385 J/g°C. You can use the formula Q = mcΔT, where Q is the heat absorbed, m is the mass, c is the specific heat capacity, and ΔT is the change in temperature. Plugging in the values, you can calculate the heat absorbed by the copper.
How is stoichiometry used to calculate energy absorbed when a mass liquid boils?
Grams liquid × mol/g × Hvap
How much energy is absorbed when 356 g of ethanol 46.0 g molboils The heat of vaporization of ethanol is 38.6 kJ mol?
To calculate the energy absorbed, first convert the mass of ethanol from grams to moles. 356 g of ethanol is 356/46.0 = 7.74 moles. Then, multiply the moles of ethanol by the heat of vaporization: 7.74 mol * 38.6 kJ/mol = 298.56 kJ of energy absorbed.
When 30 grams of water is converted into steam how much heat is absorbed?
q = mHvq = heatm = mass (30g)Hv = heat of vaporization (2,260J/g)q = (30g)(2,260J/g)q = 67,800JWhen 30 grams of water is converted into steam, how much heat is absorbed?67,800J of heat, also represented as 67.8kJ of heat is absorbed.
How much energy in kilocalories is absorbed when 9.0 mol of water is vaporized?
Molecular weight of water is 18 so 9 moles is 162 grams. Latent heat of vaporisation is 550 cal/gram, so the amount of heat is 89100 cal or 89.1 kcal.
How many kilo calories are in one gram of vitamin A?
Foods contain fats, carbohydrates and proteins. These nutrients provide energy and this energy is measured in kilocalories. Vitamin A is also a nutrient but it is not a fat, carbohydrate or protein. It is not measured in kilocalories. So, the answer to your question is that vitamin A contains 0 grams of kilocalories.
Do grams measure the amount of energy in food?
No, grams measure the weight or mass of a substance. The amount of energy in food is measured in calories or joules. The energy content is determined by the macronutrients (such as carbohydrates, proteins, and fats) present in the food.
How many kilocalories is equal to one kilogram?
kilocalories I think you mean? This is not equivalent to a kilogram. calories are a measure of energy while grams are a measure of weight.3500 k calorie = 1pound&1 kilogram = 2.20462262 poundsDo the math. lol!!!!
How many kilocalories calories are in a meal that has 15 grams of fat 12 grams of protein and 50 grams of carbohydrate?
385
How many kilocalories are in 100 grams of food?
7 Million!!!!!! Muahahahahahaha
How many kilocalories is provided by 10 grams of pure alcohol?
Well, isn't that a fascinating question! You see, alcohol provides about 7 calories per gram, so 10 grams of pure alcohol would provide approximately 70 kilocalories. It's important to remember to enjoy everything in moderation and take care of yourself, just like we take care of our happy little trees.
How is Stoichiometry use to calculate energy absorbed when a mass of liquid boils?
Grams liquid × mol/g × Hvap
How is stoichiometry used to calculate energy absorbed when mass of solid melts?
Grams solid × mol/g × Hfusion
The specific heat of gold is 0.031 caloriesgram and degC. If 10.0 grams of gold were heated and the temperature of the sample changed by 20.0 and degC how many calories of heat energy were absorbed by?
The needed heat is:Q = 10 x 20 x 0,031 = 6,2 calories
How much heat is absorbed by 1.0 g of iron when its heated to 15 degrees celsius?
The specific heat capacity of iron is 0.449 J/g°C. To calculate the heat absorbed, use the formula Q = mcΔT, where Q is the heat absorbed, m is the mass in grams, c is the specific heat capacity, and ΔT is the temperature change. Plugging in the values, the heat absorbed by 1.0 g of iron heated to 15°C is 6.735 J.
