Answer:
Relative error = 0.35
observed value = 8.775
Explanation:
given data:
Actual value = 13.5 L
Percentage of error=35%
Relative error can be determined as follow:
Absolute error = actual value - observed value
Percentage of error
Then relative error
Relative error
Then absolute error =
Therefore experimental measurement value(observed value)
= actual value - absolute error
=13.5 - 4.725 = 8.775
Answer:
480.40 g.
Explanation:
- According to the balanced equation:
<em>2 SO₂(g) + O₂(g) → 2 SO₃(g),</em>
it is clear that 2.0 moles of SO₂ react with 1.0 mole of oxygen to produce 2.0 moles of SO₃.
- We can get the no. of moles of SO₃ produced:
∵ 2.0 moles of SO₂ produce → 2.0 moles of SO₃, from the stichiometry.
∴ 6.0 moles of SO₂ produce → 6.0 moles of SO₃.
- Then, we can get the mass of the produced 6.0 moles of SO₃ using the relation:
<em>mass = no. of moles x molar mass of SO₃</em> = (6.0 moles)(80.066 g/mol) = <em>480.396 g ≅ 480.40 g.</em>
