How many liters of ammonia gas can be formed from the reaction of 150 L of hydrogen gas? Assume that there is complete reaction of hydrogen gas with nitrogen gas and that all measurements are made at the same temperature and pressure.
I understand the rules for significant figures with multiplication/division, and adding/subtracting. But I am unsure of what to do when there is both multiplication and/or division, and adding and/or subtracting in the same question?
