Question

the label on a bottle of medicine reads \each 5 ml teaspoonful contains glucose, 1.87 g, levulose, 1.87 g; and phosphoric acid, 22.2 mg.\
a. find the amount of phosphoric acid in the recommended dosage of two teaspoons.
b. if the bottle contains 5 ounces, find the quantity of phosphoric acid in the bottle. (1 oz ≈ 30 ml; 1 tsp ≈ 5 ml)

a. there are 44.4 mg of phosphoric acid in two teaspoons
(simplify your answer. type an integer or a decimal.)

b. there are \\(\square\\) mg of phosphoric acid in the bottle
(simplify your answer. type an integer or a decimal.)

Explanation:

Step1: Find total mL in the bottle

Given 1 oz ≈ 30 mL, and the bottle has 5 ounces. So total mL = 5 * 30 = 150 mL.

Step2: Find number of teaspoons in the bottle

Since 1 tsp ≈ 5 mL, number of teaspoons = 150 / 5 = 30 tsp.

Step3: Find phosphoric acid per tsp

From the label, 1 tsp (5 mL) has 22.2 mg of phosphoric acid.

Step4: Calculate total phosphoric acid in the bottle

Total phosphoric acid = 30 * 22.2 = 666 mg.

Answer:

666
