Answer:
Explanation:
-We convert Ca(OH)₂ grams to moles using its <em>molar mass</em>:
- 31.82 g ÷ 74.093 g/mol = 0.43 mol
-We convert K₂SO₃ moles to grams using its <em>molar mass</em>:
- 3.2 mol * 158.26 g/mol = 506.4 g
-One formula unit of HCl is HCl. We convert molecules to moles using <em>Avogadro's number</em>:
- 7.25x10²³ molecules ÷ 6.023x10²³mol/molecules = 1.20 mol
-At STP, <em>one mol of any gas occupies 22.4 L</em>:
- 46.6 L * 1 mol / 22.4 L = 2.080 mol
