Question
What is the dilution when we add 3 ml of stock to 27 ml of water?
Solution
The dilution is calculated by dividing the total volume by the volume of the stock.
Step 1: Identify the total volume. The total volume is the volume of the stock plus the volume of the water. In this case, 3 ml (stock) + 27 ml (water) = 30 ml (total volume).
Step 2: Divide the total volume by the volume of the stock. In this case, 30 ml (total volume) / 3 ml (stock) = 10.
So, the dilution of the stock in the water is 1:10.
