Question

Butane reacts with oxygen to produce carbon dioxide and water following the equation given below.

If 174.0 kg of butane is mixed with 320.0 kg of , the volume of water formed in litres is . (Nearest integer)

[Given: (a) Molar mass of C, H, O are 12, 1, 16 g mol⁻¹ respectively, (b) Density of water = 1 g mL⁻¹]

Strategy:
 Identify the limiting reagent in the combustion of butane. Use the stoichiometry ( ratio between butane and water) to find the moles of water formed, then convert to volume using density.

Step 1: Calculate initial moles
- Moles butane (, ) .
- Moles  () .

Step 2: Identify Limiting Reagent
Ratio .
To react  butane, we need  .
Since we have , Oxygen is the limiting reagent.

Step 3: Calculate yield of water
From  :

Nearest integer is 138.
