What mass in kg of NH3 must be used to produce 4.4 multiplied by 106 kg HNO3 by the Ostwald process, assuming 100% yield in each reaction?

This is a long problem to try to explain on this forum. Here is a site that shows you how to go through a simple stoichiometry problem (which this is) but you can just solve it more than once (or you can work out the proportions of NH3 initially to HNO3 in the end and just do the problem once).
