PLSS HELP

Which of the following is the correct formula to calculate percent by mass? (5 points)
O [Mass of solution (g) = mass of solute (9)] x 100
O [Mass of solute (9) = mass of solution (9)] < 100
[Mass of solute (g) - mass of solution (9)] x 100
O [Mass of solution (g) + mass of solute (9)] x 100

Answer 1

Answer: The equation for percent by mass is
`\text{Percent by mass}=\frac{\text{Mass of solute}}{\text{Mass of solution}}* 100`

Step-by-step explanation:

A solution consists of solute and solvent.

A solute is defined as a component that is present in a smaller proportion.

A solvent is defined as a component that is present in a larger proportion.

Concentration is defined as the amount of solute present in the given amount of solution or solvent.

The percent by mass is defined as the concentration of a solute where the ratio of the mass of solute is taken with respect to the mass of solvent multiplied by 100.

The equation used is:

`\text{Percent by mass}=\frac{\text{Mass of solute}}{\text{Mass of solution}}* 100`
