Question

Propane gas burns according to the following exothermic reaction: C3H8(g) + 5O2(g) → 3CO2(g) + 4H2O(g) ΔrH° = -2044 kJ/mol. What mass of propane gas is necessary to heat 1.7 L of water from room temperature (25.0 °C) to boiling (100.0 °C)? Assume that during heating, 14% of the heat emitted by the propane combustion goes to heat the water. The rest is lost as heat to the surroundings.

Step 1

7 L of water from 25.0 °C to 100.0 °C. Given: Volume of water (V) = 1.7 L Initial temperature (T1) = 25.0 °C Final temperature (T2) = 100.0 °C Density of water = 1 g/mL Specific heat capacity of water = 4.18 J/g°C First, calculate the mass of water: 1.7 L * 1 g/mL Show more…
