Question

In the important industrial process for producing ammonia (the Haber Process), the overall reaction is:

N2(g) + 3H2(g) → 2NH3(g) + 100.4 kJ

A yield of NH3 of approximately 98% can be obtained at 200°C and 1,000 atmospheres of pressure.

How many grams of N2 must react to form 1.7 grams of ammonia, NH3?

0.51 g
1.0 g
1.4 g
2.8 g

Answer 1

i think it's 1.0 g but i'm not sure..

Answer 2

can you tell molar mass of N2 and NH3

Answer 3

28
17
idk hahaha

Answer 4

because N is 14 and H is 1
if im correct.

Answer 5

yaaa ur right

Answer 6

so 1.0 is correct.? or am i doing this wrong..

Answer 7

now from equation i can write
17*2 gram of ammonia is synthesized by 28 g of N2
then 1.7 gram of ammonia is synthesized by =28*1.7/34

Answer 8

ahh, 1.4. got it

Answer 9

great :)

Answer 10

thanks.(:
