Hello!

The mass of NH₃ produced by the complete reaction of 2,55 g of H₂ is 14,3622 g

To calculate the mass of NH₃ produced in the chemical reaction we need to use the following conversion factor, to go from the mass of H₂ to the mass of NH₃, using the reaction coefficients for the reagents and the products, and the molar masses of each compound:

[tex]2,55gH_2* \frac{1 mol H_2}{2,0159 g H_2}* \frac{2 mol NH_3}{3 mol H_2}* \frac{17,031 g NH_3}{1 mol NH_3}=14,3622 g NH_3 [/tex]

Have a nice day!
