Question

Which type of concentration is calculated when the grams of solute is divided by the grams of the solution, and the result is multiplied by 1 000 000?(1) molarity (2) parts per million

(3) percent by mass (4) percent by volume

Answer 1

The concentration calculated when the grams of solute is divided by the grams of the solution and the result is multiplied by 1,000,000 is parts per million (ppm). Parts per million (ppm) is a unit of concentration that represents the number of grams of solute per 1,000,000 grams of solution.

Step-by-step explanation:

The concentration calculated when the grams of solute is divided by the grams of the solution and the result is multiplied by 1,000,000 is parts per million (ppm).

Parts per million (ppm) is a unit of concentration that represents the number of grams of solute per 1,000,000 grams of solution. It is commonly used to express the concentration of very dilute solutions.

For example, if there are 500 grams of solute in a solution that has a total mass of 1,000,000 grams, the concentration would be 500 ppm.

Answer 2

The correct answer is option 2. One way of expressing concentration is by expressing it by parts per million or ppm. It is calculated by dividing the grams of solute and the grams of the solution, and the result is multiplied by 1 000 000. Parts per million is equal to 1 milligram of solute per kilogram of solution.
