When gaseous nitrogen and gaseous hydrogen are reacted at high temperatures in the presence of a catalyst, ammonia (and no other product) is formed. If a chemical plant has to synthesize 450 kg of ammonia, what mass (in kilograms) of hydrogen has will be required, assuming 100% yield? (Use molar masses: hydrogen = 10 and nitrogen = 14,0 g/mol.) Give your answer to 2 significant figures.
