Question

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 ml
sample 2: 1.4 l
sample 3: 30.00 fluid ounces

Explanation:

Step1: Convert Sample 1 to liters

We know that \(1\space L = 1000\space mL\), so to convert \(250\space mL\) to liters, we divide by \(1000\).
\(250\space mL=\frac{250}{1000}\space L = 0.25\space L\)

Step2: Convert Sample 3 to liters

We know that \(1\space fluid\space ounce\approx0.0295735\space L\). So for \(30.00\space fluid\space ounces\), we multiply by this conversion factor.
\(30.00\space fluid\space ounces\times0.0295735\space L/fluid\space ounce\approx0.887205\space L\)

Step3: Sum up all the volumes

Now we add the volumes of the three samples in liters.
Total volume \(= 0.25\space L+ 1.4\space L+0.887205\space L\)
\(=0.25 + 1.4+0.887205\)
\(=2.537205\space L\) (we can round to a reasonable number of decimal places, for example, \(2.54\space L\) or keep more precision)

Answer:

The total volume of liquid the researcher has is approximately \(2.54\space L\) (or more precisely \(2.537205\space L\)) after converting all volumes to liters and summing them: \(250\space mL = 0.25\space L\), \(30.00\space fluid\space ounces\approx0.887205\space L\), and \(0.25 + 1.4+0.887205 = 2.537205\space L\).
