The Lab Report Assistant is simply a summary of the experiment’s questions, diagrams if needed, and data tables that should be addressed in a formal lab report. The intent is to facilitate students’ writing of lab reports by providing this information in an editable file which can be sent to an instructor. Exercise 1: Measuring Length, Weight, Volume, and Temperature Try the following conversions for practice. 240,000 ng =0.24 mg =0.00024 g 50 cm…show more content…
Provide the calculation steps, including the conversion factor that would be needed to convert the following measurements, and the final answers. Use US and liquid units where appropriate. 3 cups = .711 L 7,893 mg = .0174 lb 2.25 oz = 66.53 cc 36ºC = 96.8 ºF 7893mg*(1lb/453592mg)=0.0174lb 36ºC*(9/5)+32=96.8ºF (96ºF-32)*(5/9)=35.56ºC 7893mg*(1lb/453592mg)=0.0174lb 36ºC*(9/5)+32=96.8ºF (96ºF-32)*(5/9)=35.56ºC 3 cups*(.237L/1cup)=.711L 2.25oz*(29.57cc/1oz)=66.53cc 145,000uL*(1tsp/4928.92uL)= 29.42tsp 3 cups*(.237L/1cup)=.711L 2.25oz*(29.57cc/1oz)=66.53cc 145,000uL*(1tsp/4928.92uL)= 29.42tsp 145,000 uL = 29.42 tsp 96ºF = 35.56 ºC D. What advantages does the metric system have over the English method of measurement? What are the disadvantages? The metric system is advantageous because it has a base of ten, making measurements easier to take, read, understand, and convert. The prefixes are also standard so they transfer between all measurements. Also, more countries use the metric system whereas basically only the US uses the English method. The main disadvantage of the metric system is that Americans have not grown up with these measurements so they are harder to picture and
