Expert Solution

Part A
1.3 ppb means 1.3 g Cu in ml solution or L solution.
Atomic mass of Cu is 63.5 g/mol
Number of moles of Cu moles
Molarity of the solution is the ratio of the number of moles of copper to the volume (in L) of solution.
Molarity
Part B
Volume of water
Mass copper

solve only b.) and c.) The allowable concentration of acetone in drinking water is 0.05 mg/L. With 64 samples you measure an average of 0.045 mg/L with a sample standard deviation of 0.02 mg/L. Can you say at the 90% confidence level that the water meets an acceptable standard? How many samples would you need to meet the standard at 99% confidence assuming the standard deviation stays the same? (solve on Rstudio please) There is a rumor that Fairway gets...

Part A A copper pot of mass 2.5 kg contains 5.2 litres of water (i.e. 5.2 kg) at room temperature (200C). An iron block of mass 9.4 kg is dropped into the water and when the system comes into thermal equilibrium, a temperature of 380C is measured. What is the initial temperature of the iron block? Give your answer in oC to three significant figures. Part B Iron has a specific heat that is larger than that of copper. A...

One water sample form a home in Flint had lead levels of 13,200 ppb (part per billion) (See Chemical & Engineering News; February 11, 2016; vol. 97; issues 7; pp 26-29). All samples from the same home had more than 300 ppb, even after flushing. The average of several samples that were taken from the home was 2,000 ppb. If ppm is equivalent to micrograms/liter, then how many grams of lead were in each liter of water? Why is it...

Arsenic concentration in public drinking water is a potential health risk. An article in Arizona Republic (May 27, 2001) reported drinking water Arsenic concentrations in ppb (parts per billion) for 10 Metro Phoenix communities and 10 communities in Rural Arizona. The summary statistics for Metro Phoenix are; sample mean equals 12.5, and sample standard deviation equals 7.63. The summary statistics for Rural Arizona are; sample mean equals 27.5, and sample standard deviation equals 15.3. Test if there is any significant...

Assume that a chemical of concern has a concentration of 12 mg/L in drinking water. Determine the dose of the chemical for adults and children. What is the cancer risk associated with this exposure if the slope factor is determined to be 0.065 (mg/kg-d)-1 for oral exposure? If 10,000 individual consumed this water over their lifetime what number would likely get cancer?

Trace metals in drinking water affect the flavor and an unusually high concentration can pose a health hazard. We obtain the following data for 9 glasses of water. Each glass contained the same amount of water. We look at the zinc concentration (mg/L) in bottom water and the zinc concentration in surface water for each glass. It is fine to round any standard deviations to 2 decimals. Glass 1 2 3 4 5 6 7 8 9 Bottom Water .48...

In an experiment, 698 g of water is in a copper calorimeter cup of mass 204 g. The cup and the water are at an initial temperature of 11.3 oC. An unknown material with a mass of 411 g at a temperature of 421.8 oC is placed in the water. The system reaches thermal equilibrium at 31.1 oC. What is the specific heat of the unknown material?

A copper calorimeter can with mass 0.555kg contains 0.165kg of water and 1.90
