18 Calculate how many mg of tetracycline are required to make 75.0 mL of a 12.5mg/mL solution of tetracycline. Record the correct amount rounded to one decimal place. Type your answer... Numeric 2 points

## Step 1<br />The problem involves calculating the amount of tetracycline required to make a solution of a given concentration. The concentration of the solution is given as 12.5 mg/mL, which means that each milliliter of the solution contains 12.5 mg of tetracycline.<br /><br />## Step 2<br />To find the total amount of tetracycline required, we need to multiply the concentration of the solution by the volume of the solution. In this case, the volume of the solution is 75.0 mL.<br /><br />### **The formula to calculate the total amount of tetracycline required is:**<br />### \( Total\, amount\, of\, tetracycline = Concentration\, of\, solution \times Volume\, of\, solution \)<br /><br />## Step 3<br />Substitute the given values into the formula:<br /><br />### \( Total\, amount\, of\, tetracycline = 12.5\, mg/mL \times 75.0\, mL \)<br /><br />## Step 4<br />Calculate the total amount of tetracycline required.
