Final answer:
A mouthwash contains 22.5% (ν/ν) alcohol by volume. This means that in every 100 ml of mouthwash, there are 22.5 ml of alcohol. Therefore, in a 335 ml bottle, it would contain approximately 75.375 ml of alcohol.
Step-by-step explanation:
This is a mixtures and solutions problem in Chemistry, focusing on percentages and volumes. When it says 22.5% (ν/ν) alcohol by volume, it means 22.5 ml of alcohol is present in every 100 ml of mouthwash. So if you have 335 ml of mouthwash, to find the quantity of alcohol, you would multiply 335 ml by 22.5%.
To calculate, convert the percentage to a decimal by dividing it by 100. So, 22.5% becomes 0.225. Multiply 335 ml (volume of mouthwash) by 0.225 (percentage of alcohol). Therefore, the volume of alcohol is 75.375 ml.
