Determining the equation of a reaction

If 7.85 x 10 to the 24th power Sc atoms react with excess CaO, how many grams of each product will form? You will need to determine the equation of the reaction. Please show steps to solve the problem. Thank you.

Solution Preview

3CaO + 2Sc = Sc2O3 + 3 Ca
7.85 * 10^(24) Sc == 7.85 * 10^(24)/(Avogadro number) moles of Sc
= 7.85 * 10^(24)/(6.023*10^(23)) moles of Sc
= 13.03 ...

Solution Summary

This solution provides step-by-step solutions for finding grams of a product as well as the equation for the reaction.
