The molar mass of \( \mathrm{C}_{3} \mathrm{H}_{8} \mathrm{O}_{2} \) is \( \begin{array}{l}29.0 \mathrm{~g} . \\ 69.0 \mathrm{~g} . \\ 76.0 \mathrm{~g} . \\ 60.0 \mathrm{~g} . \\ 52.0 \mathrm{~g} .\end{array} \)

To calculate the molar mass of \( \mathrm{C}_{3} \mathrm{H}_{8} \mathrm{O}_{2} \), you’ll want to sum the atomic masses of its constituent elements. Carbon (C) has an atomic mass of 12.01 g/mol, Hydrogen (H) is 1.01 g/mol, and Oxygen (O) is 16.00 g/mol. There are 3 carbons, 8 hydrogens, and 2 oxygens, so the calculation would look like this: \( (3 \times 12.01) + (8 \times 1.01) + (2 \times 16.00) = 36.03 + 8.08 + 32.00 = 76.11 \) g/mol. Therefore, the molar mass is approximately 76.0 g/mol! Understanding molar mass is crucial for many applications in chemistry, especially when preparing solutions or conducting reactions. For example, if you're making a specific molarity solution of \( \mathrm{C}_{3} \mathrm{H}_{8} \mathrm{O}_{2} \), knowing the molar mass allows you to weigh out the correct amount to achieve your desired concentration. This is especially important in fields like pharmaceuticals or food science, where precision is key to safety and efficacy!
