Question

Ammonia, an important source of fixed nitrogen that can be metabolized by plants, is produced using the haber process in which nitrogen and hydrogen combine. n2(g) + 3h2(g) = 2nh3(g) how many grams of nitrogen are needed to produce 325 grams of ammonia?

a.1070 g
b.535 g
c.267 g
d.178 g
e.108 g

Answer 1

Hello!

This is the chemical reaction for the Haber Process:

N₂(g) + 3H₂(g) → 2NH₃(g)

From the chemical coefficients in this reaction and the molar masses, we can write the following conversion factor to calculate the grams of nitrogen that are needed to produce 325 grams of ammonia:


`325gNH_3* (1 mol)/(17,031 g)* (1 mol N_2)/(2 moles NH_3)* (28,0134 g N_2)/(1 mol N_2)=267,29 g N_2`

So, there are 267,29 g of N₂ required to produce 325 grams of ammonia.

Have a nice day!
