Following a 250-mg intravenous bolus dose of a drug, the resulting drug concentrations in plasma declined in an apparent monoexponential manner. Extrapolation of the log-linear elimination slope to time zero yielded a concentration of 12.5 mg/mL. At 2 h after dosing, the concentration had declined to 6.25 mg/mL. What is the plasma clearance of the drug

a. the law of proportion states the combination of 2 atoms in a specific ratio to produce multiple compounds such as the given statement of question ‘1st compound contains 88.8 % cu ’ indicates 88.8 g of cu is present along with 11.2 g oxygen in 100 g of compound whereas the statement ‘2st compound contains 79.9 % cu ’ indicates 79.9 g of cu is present along with 20.1 g oxygen in 100 g of compound

1st compound contains 88.8 g cu

for cu

m = 63 g /mol

atomic % = 88.8 /63 = 1.42

for o

m = 16 g /mol

atomic % = 11.2 /16 = 0.7

b. the emperical formula of 1st compound is

cu1.4o0.7

cu2o
