HOPE THIS HELPS. :D
Heat fusion is the amount of energy required to convert one mole of ice into water, 16650J is per 50g so if we divide 16650 by 50 we find it per gram: 16650/50 = 333J/g or 0.33KJ/g
hope that helps :)

As Scientist B did the experiment incorrectly tht is Gretchen measured out 5 grams of aluminum and heated it with excess fluorine gas.
<h3>What is the stoichiometry in chemistry?</h3>
Chemical Stoichiometry refers back to the quantitative look at of the reactants and merchandise concerned in a chemical reaction. The word “ stoichiometry” is derived from the Greek word “stoikhein” which means detail and “metron” which means measure.
- As scientists used the insufficient amount of Al due to which weight of Al2O3 is not found ane caused the high error.
- It includes stoichiometry to show how the scientist can make the experiment correct by the production of 19 g of ALF3 which is 26.98 x 19 / 83.98 g of Al.
- so the mass is 610 g of Al that would be the correct amount.
