mass of Cl₂ = 8.61 grams
Explanation:
We have 2.75 of chlorine (Cl₂) which is gas. If we assume that it is behaving like an ideal gas and we work under standard conditions, we can use the following equation.
number of moles = volume / 22.4 (L / mole)
number of moles of Cl₂ = 2.75 / 22.4 = 0.123 moles
number of moles = mass / molecular weight
mass = number of moles × molecular weight
mass of Cl₂ = 0.123 × 71 = 8.61 grams

Answer:
4.65 L of NH₃ is required for the reaction
Explanation:
2NH₃(g) + H₂SO₄(aq) → (NH₄)₂SO₄(s)
We determine the ammonium sulfate's moles that have been formed.
8.98 g . 1mol / 132.06 g = 0.068 moles
Now, we propose this rule of three:
1 mol of ammonium sulfate can be produced by 2 moles of ammonia
Therefore, 0.068 moles of salt were produced by (0.068 . 29) / 1 = 0.136 moles of NH₃. We apply the Ideal Gases Law, to determine the volume.
Firstly we do unit's conversions:
27.6°C +273 = 300.6 K
547.9 mmHg . 1 atm / 760 mmHg = 0.721 atm
V = ( n . R . T ) / P → (0.136 mol . 0.082 L.atm/mol.K . 300.6K) / 0.721 atm
V = 4.65 L
Colligative properties are properties of solutions that result from adding solute to a solvent and that depend on the concentration of solute particles, but independent of the identity of the solute molecules or ions. The four colligative properties are boiling point elevation, freezing point depression, osmotic pressure, and vapor pressure lowering.
