Question

How many liters of fluorine gas, at standard temperature and pressure, will react with 23.5 grams of potassium metal? Show all of the work used to solve this problem.

2 K + F2 ---> 2 KF

jfraser · Answer

turn the grams of K into moles of K, then use the mole ratio from the balanced equation to find moles of F2.
Once you have moles of F2, use the molar volume of 22.4L/mol to find volume of F2.
