Answer

(a) There are 3.74 grams of glucose in a dosage of two teaspoons. (b) There are 44.88 grams of glucose in the bottle.

Work Step by Step

(a) We can find the amount of glucose in a dosage of 2 teaspoons. $1.87~g/tsp \times 2~tsp = 3.74~g$ There are 3.74 grams of glucose in a dosage of two teaspoons. (b) $1~oz \approx 30~mL$ $1~tsp = 5~mL$ We can find the number of teaspoons of medicine in the bottle. $4~oz = \frac{4~oz}{1}\times \frac{30~mL}{1~oz}\times \frac{1~tsp}{5~mL}$ $4~oz = 24~tsp$ We can find the amount of glucose in the bottle. $1.87~g/tsp \times 24~tsp = 44.88~g$ There are 44.88 grams of glucose in the bottle.
