Question

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 width of a football field = 48. □ the volume of water in a tall glass = 0.5 □ the mass of a newborn baby = 3000. □ the height of a typical room ceiling = 3. □

Explanation:

Step1: Analyze the width of a football field

The width of a football field is typically measured in meters. 48 meters is a reasonable width for a football field. So the unit here is $m$ (meter).

Step2: Analyze the volume of water in a tall glass

The volume of water in a glass is often measured in liters. 0.5 liters is a reasonable volume for a tall glass. The unit for volume here is $L$ (liter, and liter is a unit approved for use with SI for volume of liquids in common contexts).

Step3: Analyze the mass of a newborn baby

The mass of a newborn baby is typically measured in grams. 3000 grams (which is 3 kilograms) is a reasonable mass for a newborn. So the unit here is $g$ (gram).

Step4: Analyze the height of a typical room ceiling

The height of a room ceiling is typically measured in meters. 3 meters is a reasonable height for a room ceiling. So the unit here is $m$ (meter).

Answer:

• the width of a football field = 48. $m$
• the volume of water in a tall glass = 0.5 $L$
• the mass of a newborn baby = 3000. $g$
• the height of a typical room ceiling = 3. $m$
