a) C32H66 of concentration in the winter rainwater having 1.50 ppb. Suppose that the density of water having the 1.00 g/mL; Calculate the concentration of C32H66 which is expressed as n M. Hint: If % = parts per 100, then Explain what would the ppb or parts per billion equal? (Molecular weight C32H66 = 450.88)
b) The concentration of glucose,C6H12O6 in the human blood which is having the ranges from about 80 mg/100 mL before the meals up to 120 mg/100 mL after eating. A certain blood sample had a glucose concentration of 97mg/100 mL. Communicate the concentration in mM. (Where the molecular weight glucose = 180.16)
c) The drinking water having the 1.6ppm fluoride (F-) for avoidance of tooth decay. A certain reservoir contained a predictable 1.67 x 1012 mL water. Determine the number of kg of NaF should be added to give 1.6 ppm F-? Hint: If % = parts per 100, then Discuss what would ppm or parts per million equal? Where the formula weight NaF = 41.98817
d) Determine the number of grams of NaF are necessary to arrange the mL of 0.19 M F-? Where the formula weight 41.98817
e) Determine the number of grams of Potassium Hydrogen Phthalate, KHP, are necessary to make the 500 mL of 0.48 M KHP? Where the formula weight= 204.23
