How many grams of nh3 can be produced from 2.93mol of n2 and excess h2?

1 mol of N2 is 28 gms, thus, 2.93mol is 84 gms.

According to the equation-

N (2 + 3H (2) =  2NH(3) 

28gms (1mol) of N2 produces 34gms of NH3

so, 84gms of N2 will produce:

28gms of N2>34gms of NH3
84gms of N2> 28/84 = 34 / x

x= (34*84) / 28

102gms

The  grandmother cell  is a hypothetical  neuronthat represents a complex but specific concept or object.[1]  it activates when a person "sees, hears, or otherwise sensibly discriminates"[2]  a specific entity, such as his or her grandmother. the term was in use at least as early as 1966 amongst staff and students in the department of experimental psychology, university of cambridge, england. a similar concept, that of the  gnostic neuron, was proposed two years later
