QUESTION 27 A hydrocarbon (a compound containing only carbon and hydrogen) is analyzed using a combustion analysis. If a 2.55 g sample of the hydrocarbon produced 8.00g of carbon dioxide and 3.28 g water, what is a possible formula of this hydrocarbon? The molar mass of carbon dioxide (CO2) is 44.01 g-mol-1, and the molar mass of water (H20) is 18.02 g-mol1. O C2H2 (with an empirical formula of CH) O C4H10 (with an emoirical formula of C2H5) O C6H12 (with an empirical formula of CH2) O C15H6 (with an empirical formula of C5H2)

QUESTION 27
A hydrocarbon (a compound containing only carbon and hydrogen) is analyzed using a combustion analysis. If a 2.55 g sample of the hydrocarbon
produced 8.00 g of carbon dioxide and 3.28 g water, what is a possible formula of this hydrocarbon? The molar mass of carbon dioxide (CO2) is 44.01
g-mol-1, and the molar mass of water (H20) is 18.02 g-mol-1.
O C2H2 (with an empirical formula of CH)
O C4H10 (with an emoirical formula of C2H5)
O CGH12 (with an empirical formula of CH2)
O C15H6 (with an empirical formula of C5H2)
QUESTION 28
For a 8.73 g sample of ethanol (shown in the figure), what is the percent composition by mass of carbon? The molar mass of ethanol is 46.08 g-mol-1.
