What is the percent yield of NH3 if the reaction of 26.3 g of H2 produces 79.0 g of NH3?
Anvisha [2.4K]

Answer:

\boxed{\text{53.3 \%}}

Explanation:

MM:           2.016      17.03

           N₂ + 3H₂ ⟶ 2NH3

m/g:            26.3  

1. Theoretical yield

(a) Moles of H₂

\text{Moles of H${_2}$} = \text{26.3 g H${_2}$} \times \dfrac{\text{1 mol H${_2}$}}{\text{2.016 g H${_2}$}} = \text{13.05 mol H${_2}$}

(b) Moles of NH₃

\text{Moles of NH${_3}$} = \text{13.05 mol H${_2}$} \times \dfrac{\text{2 mol NH${_3}$}}{\text{3 mol H${_2}$}} = \text{8.697 mol NH${_3}$}

(c) Theoretical yield of NH₃

\text{Mass of NH${_3}$} = \text{8.967 mol NH${_3}$} \times \dfrac{\text{17.03 g NH${_3}$}}{\text{1 mol NH${_3}$}} = \text{148.1 g NH${_3}$}

(d) Percent yield

\text{Percent yield} = \dfrac{\text{ actual yield}}{\text{ theoretical yield}} \times 100 \% = \dfrac{\text{79.0 g}}{\text{148.1 g}} \times 100 \% = \textbf{53.3 \%}\\\\\text{The percent yield is }\boxed{\textbf{53.3 \%}}

What is the volume of water needed to prepare 5000 ml of 0.1 M HCL from a stock solution of4 M
Karo-lina-s [1.5K]

Hey There :

Volume initial = ?

Volume final = 5000 mL

Molarity initial = 4 M

Molarity final = 0.1 M

Therefore :

Mi * Vi = Mf * Vf

4 * vi = 0.1 * 5000

4 vi = 500

Vi = 500 / 4

Vi = 125 mL

Answer A

Hope this helps!
