Solution 53E: Here we have to calculate the volume of wine in L We know 1 gal = 3.785 L The capacity of the barrel in L = 31 gal x 3.785L 1 gal = 117.3 L Therefore, 117.3 L of wine can hold in the barrel. (b) We have to calculate the dose of drug in mg for 185 lb person We know 1lb = 453.59 g 1000 g = 1 kg Therefore, here we convert lb to kg 185 lb = 185 lb x 453.59 x 1 kg= 83.91 kg 1 lb 1000g It is given 6 mg of drug is consumed by 1 kg of person 6 mg Dosage needed = 1 kgx 83.91 kg = 503.46 mg = 5 x 10 mg 2 Therefore, the drug dosage required for 185 lb of person is = 5 x 10 mg (c) Here we need to calculate the mileage of the automobile in miles...
