Answer:
Al2o3 grams to moles
Explanation:
You can view more details on each measurement unit: molecular weight of Al2O3 or grams This compound is also known as Aluminium Oxide. The SI base unit for amount of substance is the mole. 1 mole is equal to 1 moles Al2O3, or 101.961276 grams.
Answer:
Explanation:
Hello,
In this case, for the undergoing balanced chemical reaction:
We must first identify the limiting reactant given the 225 g of SiCl4 and 101 g of Mg. Thus, we compute the available moles of SiCl4:
Next, by using the 1:2 mole ratio between SiCl4 and Mg, we compute the moles of SiCl4 consumed by 101 g of Mg:
Thus, since less moles of SiCl4 are available, we can infer it is the limiting reactant whereas the Mg is in excess. In such a way, the produced grams of Si are computed considering the 1:1 molar ratio between SiCl4 and Si:
Best regards.
