Final answer:
To calculate the flow rate in mL/hour, we divide the amount of solution by the time in hours.
Step-by-step explanation:
To calculate the flow rate in mL/hour, we need to convert the given 20-minute period into hours by dividing it by 60. This gives us 0.33 hours. The flow rate can be calculated using the formula:
Flow Rate (mL/hour) = Amount of Solution (mL) / Time (hours)
Substituting the values, we get:
Flow Rate = 100 mL / 0.33 hours = 303.03 mL/hour
Therefore, the flow rate in mL/hour is approximately 303.03.
