We are asked to calculate the mass of the hydrocarbon sample that was combusted.
We can calculate the mass of C and H based on the products.
A sample of a hydrocarbon is combusted completely in O2(g) to produce 24.01 g CO2(g), 4.917 g H2O(g), and 342 kJ of heat.
What is the mass of the hydrocarbon sample that was combusted?
