Question

How many liters of chlorine gas, at standard temperature and pressure, will react with 15.5 grams of potassium metal? Show all of the work used to solve this problem. 
2 K + Cl2 yields 2 KCl

boldjon · Answer

Convert the mass of K into moles:  moles=massMolar mass

Use a ratio of the moles with the coefficients to find moles of Cl2

moles of KK′s coefficient=moles of Cl2Cl′2s coefficient

Now find the L, 1 mole = 22.414 L
