Question

Consider the following reaction.
2KClO3(s) → 2KCl(s) + 3O2(g)

a.) How many grams of KCl are produced from the complete reaction of 12.5 mol of KClO3?

b.) How many grams of KCl are produced from the complete reaction of 38.4 g of KClO3?

Please explain how to solve for the answer with steps, thank you!

a. the balanced equation says you get the same number of moles of KCl as you had in KClO3.

b. figure out how many moles of KClO3 is in 38.4 g (38.4/molmassKClO3)

then you get the same number of moles of KCl, then figure grams
gramsKCl= (38.4/molmassKClO3)*molmassKCl
