How many grams of Ni are formed from 55.3 g of Ni2O3?<br><br> 2Ni2O3(s)⟶4Ni(s)+3O2(g)
Neko [114]

Answer:

39.2 g

Explanation:

  • 2Ni₂O₃(s) ⟶ 4Ni(s) + 3O₂(g)

First we <u>convert 55.3 grams of Ni₂O₃ into moles of Ni₂O₃</u>, using its<em> molar mass</em>:

  • 55.3 g ÷ 165.39 g/mol = 0.334 mol Ni₂O₃

Then we <u>convert 0.334 moles of Ni₂O₃ into moles of Ni</u>, using the <em>stoichiometric coefficients of the balanced reaction</em>:

  • 0.334 mol Ni₂O₃ * \frac{4molNi}{2molNi_2O_3} = 0.668 mol Ni

Finally we <u>calculate how much do 0.668 Ni moles weigh</u>, using the<em> molar mass of Ni </em>:

  • 0.668 mol Ni * 58.69 g/mol = 39.2 g
