How many molecules are in 2.50 moles of SO2

Chemistry
1 answer:
dusya [7]3 years ago
7 0

Every compound or element has a fixed number of molecules per mole. This is given by the Avogadros number which is about 6.022 x 10^23 molecules per mole. Therefore:

 

molecules = 2.50 moles * (6.022 x 10^23 molecules / mole)

<span>molecules = 1.5055 x 10^24 molecules of SO2</span>

When 80.0 mL of a 0.812 M barium chloride solution is combined with 40 mL of a 1.52 M potassium sulfate solution, 10.8 g of bari
BabaBlast [244]

Answer:

76.1%

Explanation:

The reaction that takes place is:

  • BaCl₂ + K₂SO₄ → BaSO₄ + 2KCl

First we determine how many moles of each reactant were added:

  • BaCl₂ ⇒ 80 mL * 0.812 M = 64.96 mmol BaCl₂
  • K₂SO₄ ⇒ 40 mL * 1.52 M = 60.8 mmol K₂SO₄

Thus K₂SO₄ is the limiting reactant.

Using the <em>moles of the limiting reactant</em> we <u>calculate how many moles of BaSO₄ would have been produced if the % yield was 100%</u>:

  • 60.8 mmol K₂SO₄ * \frac{1mmolBaSO_4}{1mmolK_2SO_4} = 60.8 mmol BaSO₄

Then we <u>convert that theoretical amount into grams</u>, using the <em>molar mass of BaSO₄</em>:

  • 60.8 mmol BaSO₄ * 233.38 mg/mmol = 14189.504 mg BaSO₄
  • 14189.504 mg BaSO₄ / 1000 = 14.2 g BaSO₄

Finally we calculate the % yield:

  • % yield = 10.8 g / 14.2 g * 100 %
  • % yield = 76.1%
