Final answer:
The question involves combustion analysis to determine the amounts of carbon and hydrogen in a hydrocarbon, by measuring the masses of CO₂ and H₂O produced during combustion.
Step-by-step explanation:
The question involves a process called combustion analysis, which is used to determine the elemental composition of hydrocarbons. In this analysis, the hydrocarbon is combusted, and the amounts of carbon dioxide (CO₂) and water (H₂O) produced are measured. These measurements can be used to calculate the amounts of carbon and hydrogen in the original hydrocarbon compound.
First, convert the given masses from milligrams to grams. Then, using the molar masses of CO₂ and H₂O, determine how many moles of each gas are produced. Since each mole of CO₂ represents one mole of carbon, and every two moles of H₂O represent two moles of hydrogen, you can calculate the mass of carbon and hydrogen that were in the original sample.
