PLS HELP!!
Gnesinka [82]

Answer:

from the 1st equation:

  4NH3                  4NO

  4 *(68)                 4*30

  1216                     X  mass of NO = 536.5 g

from the 2nd Equation

  2NO           2NO2

   2*30            2* 46

   536.5          x         mass of NO2 = 822.6 grams

from the 3rd Equation

  3NO2                         2HNO3

   3*(46)                           2* (63)

     822.6                             X                mass of nitric acid = 751.06 gram

b)  % yields = ( 96.2%* 91.3% *91.4%)= 80.3%
