Question
![**Ketamine Calculation Exercise**
**Description:**
Ketamine, sometimes used as an adjuvant to general anesthesia, is available as a 1.0% (w/v) solution.
**Problem Statement:**
Calculate the mass of ketamine in 0.50 mL of this solution. Be sure your answer has a unit symbol and is rounded to the correct number of significant digits.
**Interface Elements Explained:**
1. **Input Box:**
- A text box is present for entering the calculated answer.
2. **Controls:**
- A graphical user interface (GUI) with buttons is shown below the input box:
- A square box that, when checked, may relate to additional functionality or steps (e.g., "x10" indicating multiplication by ten).
- A large "X" button possibly for clearing the input.
- A circular "undo" button for reversing the last action.
- A question mark button, likely for help or further instructions.
**Calculations Help:**
To calculate the mass of ketamine in the solution:
1. **Step 1:** Understand that 1.0% (w/v) means 1.0 g of ketamine per 100 mL of solution.
2. **Step 2:** Set up a proportion to find the mass (m) in 0.50 mL.
\[
\frac{1.0 \text{ g}}{100 \text{ mL}} = \frac{m}{0.50 \text{ mL}}
\]
3. **Step 3:** Solve for m:
\[
m = \frac{1.0 \text{ g} \times 0.50 \text{ mL}}{100 \text{ mL}}
= 0.005 \text{ g}
\]
So, the mass of ketamine in 0.50 mL of this solution is 0.005 g.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Ff2d79032-32db-4435-bc8c-34ca2691b1b6%2F6b3fcd28-dc92-4ec5-90fb-f21f202f4882%2Fa5g0jra_processed.png&w=3840&q=75)
