%23 Laboratory Experiments 15 QUESTIONS 1. Identify each of the following as measurements of length, area, volume, mass, density, time, or temperature: ³. (a) ns, (b) 10.0 kg/m³, (c) 1.2 pm, (d) 750 km², (e) 83 K, and (f) 4.0 mm

3 .A student estimated that the volume of a crucible was 28.6 mL. When the volume wasaccurately measured, the volume was 34.5 mL. What was the percent error for this estimate?(In this case, use estimated value for experimental value, and use measured value for the accepted value)

I measured a line that was 8.4 centimeters which is the same as 3.375 inches. How do I calculate the percente relative error?

12) Perform the following conversions using dimensional analysis and proper set up. Provide each answer with correct units and significant figures in the space provided. Note that you can square a length relationship to obtain an area relationship and you can cube a length relationship to obtain a volume relationship. It may be easier to treat prefixes separately. f) Convert 155 cm? to ft?
