Question
A bag can hold 2.5 L of \( 0.9 \% \) sodium chloride solution. If four patients are given 350 mL each of the solution, how much is left in the original bag? Express the answer in millilitres. Solution left \( =\square \mathrm{mL} \)

Answer
1100 mL is left in the original bag.
Solution
1. Convert the bag’s capacity to millilitres:
\[
2.5\ \text{L} = 2500\ \text{mL}
\]
2. Calculate the total volume given to the four patients:
\[
\text{Total volume administered} = 4 \times 350\ \text{mL} = 1400\ \text{mL}
\]
3. Find the remaining volume in the bag by subtracting the administered volume from the bag's capacity:
\[
\text{Solution left} = 2500\ \text{mL} - 1400\ \text{mL} = 1100\ \text{mL}
\]
The final answer is:
\[
\boxed{1100\ \text{mL}}
\]

Simplify this solution Bonus Knowledge
The original bag holds 2.5 L of solution, which is equivalent to 2500 mL. If each of the four patients receives 350 mL, then the total volume given to patients is \( 4 \times 350 \, \text{mL} = 1400 \, \text{mL} \). To find out how much is left in the bag, we subtract the total given from the original volume: \( 2500 \, \text{mL} - 1400 \, \text{mL} = 1100 \, \text{mL} \). So, the solution left \( = 1100 \, \text{mL} \).
