Below are sample questions representative of the exercises included on this worksheet and related 9.3 SI Units, Measurement, and Unit Conversion skill assessments:

Problem 1Difficulty: Mastery

A lab notebook lists a sample mass of 0.006 kg and a volume of 2.5 mL. What density should be reported in g/mL?

A2.4 g/mL

B24 g/mL

C0.0024 g/mL

D0.24 g/mL

Solution & Explanation:Convert 0.006 kg to 6 g, then divide by volume: 6 g ÷ 2.5 mL = 2.4 g/mL.

Problem 2Difficulty: Mastery

Use the temperature table shown. Which sample is warmest after all temperatures are compared in the same unit?

ASample D

BSample A

CSample C

DSample B

Solution & Explanation:Sample A is 294 K, or 20.85°C. Sample B is 22.0°C. Sample C is 292 K, or 18.85°C. Sample D is 21.4°C. Sample B is warmest.

Problem 3Difficulty: Mastery

An engineering drawing gives a target length of 0.125 m with an allowed tolerance of ±2 mm. A part measures 12.7 cm. Which statement is correct?

AThe part meets the tolerance at the upper limit.

BThe part is 2 mm above the allowed range.

CThe part is 20 mm above the allowed range.

DThe part is 2 mm too short.

Solution & Explanation:Convert the target to centimeters: 0.125 m = 12.5 cm. The tolerance ±2 mm equals ±0.2 cm, giving an allowed range of 12.3 cm to 12.7 cm. The part is exactly at the upper limit.
