When 100 g of gasoline undergoes combustion 9560 kJ of energy are released Express the heat released 9560 kJ in kilocalories?
1 kJ is approximately 0.239 kcal9560 kJ * (0.239 kcal/kJ) = 2284.84 kcal
What mass of natural gas CH4 must you burn to emit 267 kJ of heat?
First, determine the heat of combustion for CH4, which is -802 kJ/mol. Then, calculate the number of moles of CH4 needed to emit 267 kJ of heat. Finally, convert the moles of CH4 to grams using the molar mass of CH4 (16 g/mol).
How much energy is required to evaporate 5 grams toluene?
Toluene had heat of vaporization of 38.06 kJ/mol Toluene molecular mass is 92.14 g/mol You just need to convert heat of vaporization into kJ/g basis and multiply your 5 gram to get the required amount of heat.
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.
What is the molar heat of fusion of ethanol?
The molar heat of fusion of ethanol is approximately 5.02 kJ/mol. This is the amount of energy required to convert one mole of solid ethanol into liquid ethanol at its melting point of -114.1°C.
How much is 200 kj in calorese?
To convert 200 kJ to calories, you can multiply it by 0.239 to get approximately 47.8 calories.
What is 3923.7552 J into Kj?
To convert joules to kilojoules, divide by 1000. Therefore, 3923.7552 J is equal to 3.9238 kJ.
When 100 g of gasoline undergoes combustion 9560 kJ of energy are released Express the heat released 9560 kJ in kilocalories?
1 kJ is approximately 0.239 kcal9560 kJ * (0.239 kcal/kJ) = 2284.84 kcal
A 2 in piece of chocolate cake with frosting provides 1790 kJ of energy What is this in dietary Calories Cal?
To convert kilojoules (kJ) to dietary Calories (Cal), you can use the conversion factor where 1 Cal is approximately equal to 4.184 kJ. Therefore, to convert 1790 kJ to Calories, you divide by 4.184: 1790 kJ ÷ 4.184 kJ/Cal ≈ 427.5 Cal. So, a 2-inch piece of chocolate cake with frosting provides about 428 dietary Calories.
How do you convert kJ-kg-min to kJ-min?
We must assume that this is an exercise in unit analysis. To convert from kilojoule-kilogram-minute to kilojoule-minute requires you to get rid of the kilogram somehow. That means you must divide by kilograms or multiply by kg-1, which is equivalent to 1/kg.
How do I convert the latent heat of condensation of water 334 kJkg into a volumetric measurement of kJ m3?
To convert latent heat of condensation from kJ/kg to kJ/m^3, you need to consider the density of water. The density of water is approximately 1000 kg/m^3. So, multiply the latent heat of condensation (334 kJ/kg) by the density of water (1000 kg/m^3) to get the heat in kJ/m^3, which would be 334,000 kJ/m^3.
How do i convert grams to kilojoules?
To convert grams to kilojoules, you first need to know the substance's energy content, typically expressed in kilojoules per gram (kJ/g). Multiply the mass in grams by the energy content of the substance to obtain the total energy in kilojoules. For example, if a food item has 4 kJ/g and you have 100 grams, the calculation would be 100 grams × 4 kJ/g = 400 kJ.
What is the caloric value of one apple if its value in kilojoules is 283 kJ?
To convert kilojoules to calories, you can use the conversion factor where 1 kilojoule is approximately equal to 0.239 calories. Therefore, the caloric value of one apple with 283 kJ is about 67.5 calories (283 kJ × 0.239 cal/kJ).
How many calories in 150ml of semi skimmed milk?
between 17 and 20 calories
How many kilocalories of heat does an expenditure of 240kJ produce?
To convert kilojoules (kJ) to kilocalories, you can use the conversion factor of 1 kJ is equivalent to 0.239 kcal. So, 240 kJ is equal to 240 x 0.239 ≈ 57.4 kilocalories of heat.
When 100.0g of gasoline undergoes combustion 9560kj of energy are released express the heat released in kilocalories given that 4.184j is 1 cal?
To convert the energy released from kilojoules to kilocalories, we need to use the conversion factor that 1 kcal is equal to 4.184 kJ. First, convert 9560 kJ to kcal: 9560 kJ x (1 kcal / 4.184 kJ) = 2282.3 kcal So, when 100.0g of gasoline undergoes combustion, 2282.3 kcal of energy are released.
What is the value of G at 500 K if H27kJMol and S0.09kJ(molK)?
To find the Gibbs free energy change (ΔG) at 500 K, we can use the equation ΔG = ΔH - TΔS. Given that ΔH = -27 kJ/mol and ΔS = 0.09 kJ/(mol·K), we first convert the temperature to Kelvin (which is already given as 500 K). Then, substituting the values: ΔG = -27 kJ/mol - (500 K × 0.09 kJ/(mol·K)) = -27 kJ/mol - 45 kJ/mol = -72 kJ/mol. Thus, the value of G at 500 K is -72 kJ/mol.
