Question

Edwin fills 15 test tubes with a solution. Each test tube contains 150 milliliters of solution.

How many liters of solution in all is there in the test tubes?

Responses

2.25 L
2.25 L

22.5 L
22.5 L

225 L
225 L

2,250 L
2,250 L

Answer 1

To calculate the total volume of the solution in liters, follow these steps:

1. **Calculate the total volume in milliliters**:
\[
15 \text{ test tubes} \times 150 \text{ mL/test tube} = 2250 \text{ mL}
\]

2. **Convert milliliters to liters**:
Since 1 liter = 1000 milliliters, we convert by dividing the total milliliters by 1000.
\[
2250 \text{ mL} \div 1000 = 2.25 \text{ L}
\]

So, the total volume of solution in all the test tubes is **2.25 L**.
