What is an important step to determine the number of grams of SO3 that can be produced by reacting 6 moles of SO2 with oxygen in
vagabundo [1.1K]

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>

Mechanical Advantage may be calculated using all of the following except ___.
kotegsom [21]
The only exception of calculating mechanical advantage is by multiplying resistance force by effort force. For example, in calculating the mechanical advantage of a lever, we consider its output and input forces. The equation would now be as follows:

Mechanical advantage = output force / input force
