The reaction of 25 mL of N2 gas with 75 mL of H2 gas to form ammonia via the equation: N2(g)+3H2(g)→2NH3(g) will produce __________ mL of ammonia if pressure and temperature are kept constant.

Heres an example that's kind of like this one,

 

The reaction of 50 mL of N2 gas with 150 mL of H2 gas to form ammonia via the equation:

 

 

This is Avogadro's Law in action: equal volumes of gases at the same T and P, contain equal numbers of moles. 
Here, the volume ratio of N2 to H2 is 1 to 3. 
N2(g) + 3H2(g) --> 2NH3(g) 

Incidently, the volume of the product will be 100 mL.
