4K (s) + O2 (g) ® 2K2O (s)
1a. If 0.25 moles of potassium were reacted with an excess amount of
oxygen, how many moles of K2O would be produced?
1b. How many
moles of oxygen would be required to react with excess potassium to
produce 0.35 moles of K2O?
Use the coefficients in the equation to convert from mol of one to
the mol of other.
