If 28.45 grams of ammonia are utilized for its synthesis, how many grams of hydrogen are needed? 2NO(g)+5H2(g)------>2NH3(g)+2H2O(g)

Expert Solution

Question is not clear. It is assumed that how many grams of hydrogen are needed for the synthesis of 28.45 grams of ammonia ?

Give reaction is

2 NO(g) + 5H2(g) ------> 2NH3(g) + 2 H2O(g)

5 mol 2 mol

5x 2g= 10g 2x 17g = 34 g

? 28.45 g

? = (28.45 g/ 34g) x 10g H2

= 8.37 g H2

Therefore, 8.37 grams of hydrogen are needed.
