Calcium nitrate will react with ammonium chloride at slightly elevated temperatures, as represented in the equation

Ca(NO3)2(s) + 2NH4Cl(s) ---> 2N2O(g) + CaCl2(s) + 4H2O(g)
What is the maximum volume of N2O at STP that could be produced using a 6.80-mol sample of each reactant?

WEll, 1 mole of Calcium nitrate will yield 2 moles of N2O. Each mole of gas occupies 22.4 liters.

So 6.8*2*22.4=
22.4
