Given Data:
- Mass of chloride = 1g
- Mass of chlorine in chloride = 0.42g
- Vapour density = 85
Finding Molecular Formula:
- Step 1: Calculate the molar mass of chlorine
- The molar mass of chlorine = 35.5 g/mol (approx.)
- Step 2: Calculate the number of moles of chlorine in 1g of chloride
- Number of moles of chlorine = Mass of chlorine / Molar mass of chlorine
- Number of moles of chlorine = 0.42g / 35.5 g/mol ≈ 0.0118 moles
- Step 3: Calculate the number of moles of chloride in 1g of chloride
- Number of moles of chloride = Mass of chloride / Molar mass of chloride
- Number of moles of chloride = 1g / Vapour density = 1g / 85 ≈ 0.0118 moles
- Step 4: Determine the molecular formula
- Since the number of moles of chlorine is the same as the number of moles of chloride, the molecular formula of the compound is Cl₂
Therefore, the molecular formula of the compound is Cl₂.
