In one mol of any molecular compound there are Avogadro number of molecules. Avogadro number is 6.022 x 10^23 molecules.
So in 1 mol of any mol of a molecular compound the number of molecules is 6.022x10^23 molecules.
In 4 mol of compound it would be 4 x 6.022 x 10^23
The answer comes out to be 24.088 x 10^23
Lithium, sodium, potassium, rubidium, cesium, and francium
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>
