Answer:
Moles of NO₂ = 0.158
Explanation:
SO 2 ( g ) + NO 2 ( g ) ⇄ SO 3 ( g ) + NO ( g )
According to the law of mass equation
=
⇒ 3.10 = At equilibrium [SO₃] = [NO]
⇒ [NO₂] =
⇒ [NO₂] = 0.158
So. number of moles of NO₂ at equilibrium added = 0.158
Answer is although the question should have 3 significant figures.
<h3>What is
significant figures?</h3>
Fe + CuSO4 --> Cu + FeSO4
It is already balanced
1 mol Fe : 1 mol CuSO4 : 1 mol Cu : 1 mol FeSO4
- atomic masses of Fe and Cu
Fe: 55.8 g/mol
Cu: 63.5 g/mol
number of moles = mass in grams / atomic mass = 93.7 g / 55.8 g/mol = 1.679 mol
1 mol Fe / 1 mol Cu => 1.679 mol Fe / 1.679 mole Cu
- mass of Cu in 1.679 moles Cu
mass = atomic mass * number of atoms = 63.5 g/mol * 1.679 moles = 106.6 g = 107 rounded to 3 significant figures.
