A note on the door of the cabinet says the cabinet is used to store bottles of pentane, dimethyl sulfoxide, acetone, methyl acetate, and chloroform. The chemist plans to try to identify the unknown liquid by measuring the density and comparing to known densities. First, from his collection of Material Safety Data Sheets (MSDS), the chemist finds the following information: liquid density 0.63 mL pentane db dimethyl sulfoxide 1.1 0.79 acetone 0.93 mL methyl acetate 1.5 chloroform 3 Next, the chemist measures the volume of the unknown liquid as 1797.…

Answer question number 7 on the attached document

S.P. Is an 18 month old child who weighs 20 pounds. He has atrial fibrillation and is being treated with digoxin. He is on a maintenance dose of digoxin 0.006 mg/kg/day in divided doses every 12 hours at 0800 and 2200. Calculate the dose of medication you will give this patient every morning.

A student calibrated a eudiometer by first recording the mass of the empty eudiometer followed by filling the eudiometer to the 50.00 mL line with deionized water at 22°C and recorded the mass. The mass of water was 49.012 g. What measured reading from the eudiometer would correspond to a true volume of 47.89mL?
