You use Heat of fusion... Heat=mass x heat of fusion
Heat of fusion for water: 80 cal/g so
35g x 80 cal/g= 2800 cal released.

How many grammes of salt in a liter of seawater?
At 25 degrees Celsius it's about 385 grams NaCl per liter water.
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 energy is required to raise the temperature of 15 g of water 25 degrees Celsius?
6480 calories8LBs X 15 gallons x 54 DEGREES = 6480 CALORIES
How many ml is 80 grams of cream?
80 grams of what? And at what temperature and pressure? If you are asking about water, at 1 atmosphere, at 25 degrees C, then you can say water weighs 1 gram per milliliter.
What has more thermal energy one gram of water at 75 degrees or 100 grams of water at 75 degrees?
(75'C)x(1g) < (75'C)x(100g) .'. The second option has more thermal energy.
If you have a liter of water at 50 degrees celsius sea level You heat the water so that you apply 100000 calories About how much of the water will boil Express your answer in grams?
To raise 1000 grams of water from 50 to 100 degrees requires 50 degrees x 1000 grams of heat, so the answer is 50,000 calories. Water at 100 degrees requires an additional 550 calories to convert 1 gram fully into steam. Therefore the remaining 50,000 calories can convert 50,000/550 grams into steam. So 90.9 grams become steam, and that's the answer.
What is the formula of salt that dissolved in 100 grams of water produces a solution that freezes at negative 1.40 degrees celsius with a mass of 3.9 grams?
Na3Cl2
How many calories are required to raise 8 grams of water 7 degrees Celsius?
700
How many calories does it take to heat a 100.0 grams sample of water from 24.5 degrees C to 38.2 degrees C?
38.2C-24.5C = 13.7 C change this requires 13.7 calories per gram or 1370 calories total
How is stoichiometry used to calculate energy released when a mass of liquid freezes?
Grams liquid × mol/g × Hfusion
If 75 grams of water at 30 degrees Celsius absorbs 900 calories what will be the new temperature?
105C
How many calories are needed to heat up 5 grams of water by 3 degrees Celsius?
(5)(3)= 15 calories. 1 calorie is the energy (heat) to raise 1 gram of water by 1 degree celsius, so 5 grams of water (3 degrees Celsius) = 15.
How is the Hfusion used to calculate the energy released when a mass of liquid freezes?
Grams Liquid x mol/g x Hfusion
How many calories of heat would it take to raise the temperature of 256 grams of water from 20 degrees to 99 degrees?
A calorie is the amount of heat you need to raise the temperature of one gram of water by one degree Celsius. Assuming you are raising the temperature of the water from twenty degrees Celsius to ninety-nine degrees Celsius, it would take 20,000 calories. To calculate this, subtract 20 from 99. This is the amount of degrees you need to raise the temperature of the water by. Then multiply that number by 256, the amount of water in grams. You should get 20,244 calories. In significant digits, your answer should be 20,000 calories.
How many calories are required to heat 38.2 grams of aluminum from 102 degrees celsius to 275 degrees celsius?
Specific heat for aluminium = 0.214 Heat required = 38.2 x 0.214 x (275 - 102) = 1414.24 calories
How many calories are into grams?
