How many milliliters per minute is equivalent to a rate of 50ml/hr?

To convert a rate of 50 mL/hr to milliliters per minute, you begin by recognizing that there are 60 minutes in an hour. This means you need to divide the hourly rate by the number of minutes in an hour to find the rate in milliliters per minute.

The calculation is as follows:

[

\text{Rate in mL/min} = \frac{\text{Rate in mL/hr}}{60 \text{ min/hr}} = \frac{50 \text{ mL/hr}}{60 \text{ min/hr}} = 0.8333 \text{ mL/min}

]

When rounded to two decimal points, this value is approximately 0.83 mL/min.

Understanding this conversion is crucial for dosage calculations in pharmacy, especially for intravenous medications where rates are often prescribed in hours but administered in minutes. Thus, the correct answer, which is approximately 0.83 mL/min, matches the calculated rate, affirming that the conversion process was executed correctly.
