Chapter 2, Problem 55a
Write an equality and two conversion factors for each of the following medications:
a. 10 mg of Atarax per 5 mL of Atarax syrup
Verified step by step guidance1
Step 1: Start by writing the equality that relates the given quantities of Atarax. The problem states that 10 mg of Atarax is equivalent to 5 mL of Atarax syrup. Therefore, the equality is: .
Step 2: To create the first conversion factor, divide both sides of the equality by 10 mg. This gives: . Simplify the fraction to get: .
Step 3: To create the second conversion factor, divide both sides of the equality by 5 mL. This gives: . Simplify the fraction to get: .
Step 4: Verify that both conversion factors are consistent with the original equality. For example, multiplying by should yield , confirming the accuracy.
Step 5: Use these conversion factors in dimensional analysis to convert between milligrams and milliliters of Atarax syrup as needed in future calculations.
