Since we are already given the balanced equation:
→
We can derive the molar ratios as: 1:2:1:1
That being said, we are given 0.172 moles of bromine (), so it has a ratio of 1:1 with sodium bromide (
).
So we can take from that ratio, that when 0.172 moles of bromine are used, we are, in turn, going to get 0.172 moles of sodium bromide produced.
