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 mass of a can of soda = 355. the volume of tea in a typical teacup = 0.2 the world record for the 100m dash = 9.6 the width of a two - lane road = 10.

Explanation:

Step1: Analyze mass of soda can

A typical can of soda has a volume of about 355 milliliters, and since the density of water (and soda is mostly water) is 1 g/mL, the mass is about 355 grams. So the unit for 355. (mass of soda can) is g (grams).

Step2: Analyze volume of teacup

A typical teacup's volume is around 0.2 liters? No, 0.2 liters is 200 mL, but more accurately, a teacup is about 0.2 deciliters? Wait, no, the common unit for small volumes like a teacup is liters? Wait, no, 0.2 liters is 200 mL, but actually, a typical teacup is about 200 mL, which is 0.2 liters? Wait, no, 1 liter is 1000 mL, so 0.2 liters is 200 mL. But also, the unit for volume here, the scientific unit (SI or approved). The SI unit for volume is cubic meters, but for liquids, liters (L) are commonly used (and approved for use with SI). So 0.2 L? Wait, no, 0.2 liters is 200 mL, but maybe the unit is L? Wait, no, a teacup is about 0.2 liters? Wait, no, 0.2 liters is 200 mL, which is a reasonable volume for a teacup. So the unit for 0.2 (volume of teacup) is L (liters)? Wait, no, maybe dm³? Wait, 1 liter = 1 dm³. Alternatively, maybe the unit is L. Wait, but let's check the next one.

Step3: Analyze 100m dash time

The world record for 100m dash is in seconds. So 9.6 s (seconds).

Step4: Analyze road width

The width of a two - lane road is typically in meters. So 10. m (meters).

Answer:

• the mass of a can of soda: 355 g
• the volume of tea in a typical teacup: 0.2 L (or 0.2 dm³, but more likely L)
• the world record for the 100m dash: 9.6 s
• the width of a two - lane road: 10. m

(Note: For the volume of the teacup, if we consider SI units strictly, the SI unit for volume is m³, but 0.2 m³ is too large. So liters (L) which is a derived unit approved for use with SI is more appropriate. For the mass of the soda can, grams (g) is appropriate as the SI unit for mass is kilogram (kg), but 355 kg is too large, and grams are a sub - unit of kilogram and widely used in such contexts. For the time of the 100m dash, seconds (s) is the SI unit for time. For the road width, meters (m) is the SI unit for length.)
