![The object of a general chemistry experiment is to determine the amount (in millilitres [mL]) of sodium hydroxide (NaOH) solution
needed to neutralize 1 g of a specified acid. This will be an exact amount, but when the experiment is run in the laboratory,
variation will occur as the result of experimental error. Three titrations are made using phenolphthalein as an indicator of the
neutrality of the solution (pH equals 7 for a neutral solution). The three volumes of NaOH required to attain a pH of 7 in each of
the three titrations are as follows: 82.20, 75.80, and 75.34 mL. Use a 99% confidence interval to estimate the mean number of
millilitres required to neutralize 1 g of the acid. (Round your answers to three decimal places.)

- For some measuring processes, the uncertainty is approximately proportional to the value of the measurement. For example, a certain scale is said to have an uncertainty of ±2%. An object is weighed on this scale. a) Given that the reading is 100 g, express the uncertainty in this measurement in grams. b) Given that the reading is 50 g, express the uncertainty in this measurement in grams.arrow_forward8.)

The student conducts an investigation to compare the quantity of particulate matter released from the diesel-powered buses, natural gas-powered buses, and the large and small cars as they idle waiting to pick up students. To make measurements, a small piece of white fabric is used to collect particulate matter from the tailpipe of each vehicle as it idles for five minutes. Each piece of fabric is then analyzed to measure the amount of particulate matter it collected. (i) Identify the independent variable in the investigation.
