What mass of water is needed to react with 98.7g of li3n

 moles Li3N = 98.7 g/34.8297 g/mol=2.83 

the ratio between Li3N and H2O is 1 : 3 
moles water neeeded = 2.83 x 3=8.49 
mass water = 8.49 mol x 18.02 g/mol=153.0 g 

moles NH3 produced = 2.83 
molescules of NH3 = 2.83 x 6.02 x 10^23=1.70 x 10^24 

moles NH3 (STP) = 45.0/22.4 =2.0 
moles Li3N = 2.0 
mass Li3N = 2.0 x 34.8297 g/mol=69.6 g

Ithink that the use of creativity in the sciences entails that one produce something out of nothing or from another thing. with this, i think that the he wrote down his results as four parts of the atomic theory is the manifestation of the  creativity of john dalton.

The answer is a. stable, hope i ya
