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.
