Therefore, a 100-g sample of water contains 11.2 g of hydrogen atoms and 88.8 g of oxygen atoms. A hydrocarbon is a compound that contains mostly carbon and hydrogen. Calculate the percent composition (by mass) of the following hydrocarbon: CH22 Enter the percentages of carbon and hydrogen numerically to four significant figures, separated by commas.

A student determined fluoride in a toothpaste sample using ion chromatography. A toothpaste sample of mass 0.100 g was dissolved in type I water and then quantitatively filtered through a Whatman #1 filter paper into a clean 100 ml volumetric flask. The flask was then made up to volume with type I water and mixed thoroughly.A portion of the solution was filtered through a 0.45 um filter into a sample vial for analysis. Analysis of the sample gave a fluoride concentration of 1.60 mg/l Calculate the % w/w fluoride in the original toothpaste sample. (Give your answer to 3 decimal places please)

1-1. The raw water supply for a community contains 18 mg/L total particulate matter. It is to be treated by addition of 60 mg alum (Al2(SO4)3-14H;O) per liter of water treated. Essentially, all the added alum precipi- tates represented by the following reaction: Al2(SO4)3 · 14H20 → 2 Al(OH);(s) + 3So,- + 6H* + 8H2O For a total flow of 7500 m/d, compute the daily alum requirement, the total concentration of suspended sol- ids in the water following alum addition, and the daily load of particulate solids requiring disposal (including both those initially present and those formed during treatment).

For example, CHCIBII is chiral, but CCl,BrI is achiral because some of the bonded groups are the same. If a chiral carbon atom is present, then that molecule has a non-superimposable mirror image called an enantiomer.

[4cde] c. Calculate for the mass of struvite that can be formed in the given urine sample. d. Given that the specific gravity of struvite is 1.7, determine if the amount of struvite in c can pass through the kidney. Note: less than 6mm diameter urolith can pass through the kidney. Assume that the urolith is spherically shaped. e. Using your answer in c, calculate for the number of phosphate ions in the sample.
