Concentration refers to the amount of a particular substance within a mixture or the focus of mental effort on a specific task. In scientific contexts, it typically refers to the quantitative measure of how much of a given substance is present in a solution or mixture compared to the total amount of materials. In psychological contexts, it relates to the mental capacity to focus one's attention on a particular task or set of tasks while ignoring other distractions.
