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, 21.8 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 □ mg of phosphoric acid in two teaspool
(simplify your answer. type an integer or a decimal.)
b. there are □ mg of phosphoric acid in the bottle
(simplify your answer. type an integer or a decimal.)

Explanation:

Step1: Calculate the amount of phosphoric acid in two teaspoons

Since each \(5 - mL\) teaspoonful contains \(21.8\) mg of phosphoric acid.
For two teaspoons, we use the formula \(y = 21.8\times n\), where \(n = 2\) (the number of teaspoons).
\(y=21.8\times2\)

Step2: Calculate the amount of phosphoric acid in the bottle

First, convert the volume of the bottle from ounces to milliliters. Given \(1\) oz \(\approx30\) mL, for a \(5\) - oz bottle, \(V = 5\times30=150\) mL.
Since \(1\) tsp \(\approx5\) mL, the number of teaspoons \(n=\frac{150}{5}=30\).
Using the formula \(y = 21.8\times n\), with \(n = 30\), we have \(y=21.8\times30\)

Answer:

a. \(43.6\)
b. \(654\)
