Question 2 A researcher combines three liquid samples with the volumes listed below. How much total liquid in liters does the researcher have? Include your calculations in your answer. Sample \( 1: 250 \mathrm{~mL} \) Sample \( 2: 1.4 \mathrm{~L} \) Sample \( 3: 30.00 \) fluid ounces B B

To find the total volume of liquid in liters, we first need to convert all the measurements to liters. - Sample 1: \( 250 \, \text{mL} = \frac{250}{1000} = 0.25 \, \text{L} \) - Sample 2: This is already in liters: \( 1.4 \, \text{L} \) - Sample 3: To convert fluid ounces to liters, we use the conversion factor \( 1 \, \text{fl oz} \approx 0.0295735 \, \text{L} \). Thus, \( 30.00 \, \text{fl oz} = 30.00 \times 0.0295735 \approx 0.887 \, \text{L} \) Now, we add them together: \( 0.25 \, \text{L} + 1.4 \, \text{L} + 0.887 \, \text{L} = 2.537 \, \text{L} \) So, the researcher has approximately \( 2.54 \, \text{L} \) of liquid in total. Did you know that throughout history, the measurement of liquids has been crucial? Ancient civilizations used different methods for measuring volume, and it was the Egyptians who devised a system with marked containers. Those markings laid down some of the earliest foundations for measuring liquids, linking history with our modern-day practices. If you're interested in the science behind volume conversion, there are numerous resources to dive into! Websites like Khan Academy and educational platforms focus on practical applications of measurement conversions, where you can find interactive exercises and tips to solidify your learning.
