How many grams of HCl must be used to produce 21 L of Cl2 at STP?
since 1 mole occupies 22.4L, you need
21/22.4 = 0.9375 moles of Cl2
Now check your balanced equation to see how many moles of HCl you will need. How many grams is that?
21/22.4 = 0.9375 moles of Cl2
Now check your balanced equation to see how many moles of HCl you will need. How many grams is that?
