A mass reading reading is recorded as 0.1862 + 0.0005 g. Which of the following could be the actual value? I 0.1859 g I. 0.1864 g Il. 0.1870 gI and II onlyI and III onlyII and III onlyI, II and III2. A substance with a mass of 21.325 g was placed in a graduated cylinder with an initial volume of 10.00 cm^3 and displaced the volume to 27.62 cm^3. A student carried out the following calculation to determine the density. Density g cm^(-3)=(21.325 g)/(27.62-10 cm^(3)) What is the best value the student could report for the density of aluminium? 1.21 gcm^-31.2 gcm^-31.210 gcm^-31.2103 gcm^-33. How many significant figures are there in 1.3672?23564. Density can be calculated by dividing mass by volume. 12.0 (+)/(-) 0.2 g of a metal has a volume of 7.325 (+)/(-) 0.005 cm?. How should its density be recorded using this data?1.638 (+)/(-)0.017 gcm^-31.638 (+)/(-) 0.028 gcm^-31.64 (+)/(-) 0.03 gcm^-31.64 (+)/(-) 0.02 gcm^-35. A student recorded the mass of a liquid as 0.236 g. How many significant figures are there in this value?34566. Which experimental procedure would likely lead to a large systematic error?Determining the volume of a solution using a pipetteUsing a syringe to measure the volume of 4 gasReading the volume at the bottom of a meniscusReading the volume at the top of the meniscus7. A student performs and experiment to determine the density of a sugar solution. She obtains the following results: 1.71 gcm^-3, 1.73 gcm^-3, 1.67 gcm^-3, and 1.69 gcm^-3. If the actual density of the sugar solution is 1.40 gcm^-3, which statement below best describes her resultsThe measurements involve low accuracy and low precisionThe measurements involve low accuracy and high precisionThe measurements involve high accuracy and low precisionThe measurements involve high accuracy and high precision8. What answer should be reported, with the correct number of significant figures, for the following calculation? (433.621-333.9) x 11.9001.19 x 10^31.187x 10^31.1868 x 10^31.186860 x 10^39. There are .......................significant figures in the answer to the following computation. (249.362 + 41) / 62. 498123410.
