To calculate the alcohol concentration in the final mixture, we need to determine the total volume and the amount of alcohol in the mixture.
Let's start by finding the total volume of the final mixture. We mixed 30 ml of pure alcohol with 150 ml of the original mixture, so the total volume is 30 ml + 150 ml = 180 ml.
Next, we need to determine the amount of alcohol in the mixture. Since we mixed 30 ml of pure alcohol with the original mixture, the total amount of alcohol is 30 ml.
To calculate the alcohol concentration, we divide the amount of alcohol by the total volume of the mixture and then multiply by 100%.
Alcohol concentration = (amount of alcohol / total volume) * 100%
= (30 ml / 180 ml) * 100%
= 16.67%
Therefore, the alcohol concentration in the final mixture is 16.67%.
