. Mountain climbers often brew tea by melting snow, which they heats over a stove. Our stove
burns butane (C4H10), which has a heat of combustion of -2878 kJ/mol. The temperature of the
snow is initially at -20 °C, and we need 80 °C water to brew tea.
a. How much heat is needed to turn the snow into a cup (237 mL) of water hot enough to
make a cup of tea?
b. Calculate the mass of butane needed to fuel the stove for this process
1 answer
For part A i calculated Q to be 99.1608 kJ/mol. I don't understand where to go from there though to find part b.
