question 38

Multiple Choice

Which is a correct method for determining the mass of carbon present in 0.132 grams of propane (C₃H₈) ?

• A) \(0.132 \mathrm{~g} \mathrm{C}_{3} \mathrm{H}_{8}\left(\frac{1 \mathrm{~mol} \mathrm{C}_{3} \mathrm{H}_{8}}{44.09 \mathrm{~g}}\right)\left(\frac{12.01 \mathrm{~g} \mathrm{C}}{1 \mathrm{~mole}}\right)\)
• B) \(0.132 \mathrm{~g} \mathrm{C}_{3} \mathrm{H}_{8}\left(\frac{1 \mathrm{~mol} \mathrm{C}_{3} \mathrm{H}_{8}}{44.09 \mathrm{~g}}\right)\)\(\left(\frac{3 \mathrm{gC}}{1 \mathrm{~mol} \mathrm{C}_{3} \mathrm{H}_{8}}\right)\)
• C) \(0.132 \mathrm{~g} \mathrm{C}_{3} \mathrm{H}_{8}\left(\frac{44.09 \mathrm{~mol} \mathrm{C}_{3} \mathrm{H}_{8}}{1 \mathrm{~g}}\right)\)\(\left(\frac{3 \mathrm{~mol} \mathrm{C}}{1 \mathrm{~mol} \mathrm{C}_{3} \mathrm{H}_{8}}\right)\left(\frac{12.01 \mathrm{gC}}{1 \mathrm{~mole}}\right)\)
• D) \(0.132 \mathrm{~g} \mathrm{C}_{3} \mathrm{H}_{8}\left(\frac{1 \mathrm{~mol} \mathrm{C}_{3} \mathrm{H}_{8}}{44.09 \mathrm{~g}}\right)\)\(\left(\frac{1 \mathrm{~mol} \mathrm{C}}{3 \mathrm{~mol} \mathrm{C}_{3} \mathrm{H}_{8}}\right)\left(\frac{12.01 \mathrm{~g} \mathrm{C}}{1 \mathrm{~mole}}\right)\)
• E) \(0.132 \mathrm{~g} \mathrm{C}_{3} \mathrm{H}_{8}\left(\frac{1 \mathrm{~mol} \mathrm{C}_{3} \mathrm{H}_{8}}{44.09 \mathrm{~g}}\right)\) \(\left(\frac{3 \mathrm{~mol} \mathrm{C}}{1 \mathrm{~mol} \mathrm{C}_{3} \mathrm{H}_{8}}\right)\left(\frac{12.01 \mathrm{gC}}{1 \mathrm{~mole}}\right)\)
