Questions: The symbol of an unprefixed scientific unit has been left off of each measurement in the table below. Fill in the missing unit symbols. Note: by "scientific" unit we mean the SI unit, or unit approved for use with the SI, that is most often used by chemists for each measurement. - the volume of water in a tall glass = 0.5 - the length of a high-school swimming pool = 25. - the mass of a US penny = 2.5 - the world record for the 100 m freestyle swim = 44.9

Solution Steps

Step 1: Determine the Unit for Volume

The volume of water in a tall glass is typically measured in liters (L). For small volumes, milliliters (mL) are often used. Given the value 0.5, it is reasonable to assume the unit is liters.

Step 2: Determine the Unit for Length

The length of a high-school swimming pool is typically measured in meters (m). Given the value 25, the unit is meters.

Step 3: Determine the Unit for Mass

The mass of a US penny is typically measured in grams (g). Given the value 2.5, the unit is grams.

Step 4: Determine the Unit for Time

The world record for the 100 m freestyle swim is typically measured in seconds (s). Given the value 44.9, the unit is seconds.

Final Answer

\[ \begin{array}{|c|c|} \hline \text{the volume of water in a tall glass} & 0.5 \, \text{L} \\ \hline \text{the length of a high-school swimming pool} & 25 \, \text{m} \\ \hline \text{the mass of a US penny} & 2.5 \, \text{g} \\ \hline \text{the world record for the 100 m freestyle swim} & 44.9 \, \text{s} \\ \hline \end{array} \]

\[ \boxed{ \begin{array}{|c|c|} \hline \text{the volume of water in a tall glass} & 0.5 \, \text{L} \\ \hline \text{the length of a high-school swimming pool} & 25 \, \text{m} \\ \hline \text{the mass of a US penny} & 2.5 \, \text{g} \\ \hline \text{the world record for the 100 m freestyle swim} & 44.9 \, \text{s} \\ \hline \end{array} } \]
