Question

Given the balanced equation 3H2(g)+N2(g)=2NH3(g), calculate the mass of NH3 produced by the complete reaction of 2.55g of H2

Answer 1

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:


`2,55gH_2* (1 mol H_2)/(2,0159 g H_2)* (2 mol NH_3)/(3 mol H_2)* (17,031 g NH_3)/(1 mol NH_3)=14,3622 g NH_3`

Have a nice day!
