Question

what quantity does the following measurement represent: 9.4 g/mol
○ speed
○ molar mass
○ amount
○ density
clear select

Explanation:

To determine what the measurement \( 9.4 \, \text{g/mol} \) represents, we analyze the units:

• Speed has units like \( \text{m/s} \) (distance per time), so not \( \text{g/mol} \).
• Molar mass is defined as mass (in grams) per mole of a substance, so its unit is \( \text{g/mol} \).
• Amount of substance is measured in moles, not \( \text{g/mol} \).
• Density has units like \( \text{g/cm}^3 \) (mass per volume), not \( \text{g/mol} \).

Thus, \( 9.4 \, \text{g/mol} \) corresponds to molar mass.

Answer:

B. molar mass (assuming the options are labeled with letters, and the correct option is the one with "molar mass")
