Question

What is the percentage by mass of a solution with 30.0g salt dissolved in water to make 650.0g 0f solution?

Please help​

Answer 1

The percentage by mass of a solution with 30.0g salt dissolved in water to make 650.0g 0f solution is 4.61 %

Step-by-step explanation:

The mass percentage of a solution is a measure of concentration that indicates the number of grams of solute that there are per 100 grams of solution.

The percent by mass is calculated as the mass of a component divided by the total mass of the mixture, multiplied by 100 to give a percentage.

`percentage by mass=(solute mass)/(solution mass) *100`

In this case:

• solute mass: 30 g
• solution mass: 650 g

Replacing in the definition of percent by mass:

`percentage by mass=(30 g)/(650 g) *100`

Solving:

percent by mass= 4.61 %

The percentage by mass of a solution with 30.0g salt dissolved in water to make 650.0g 0f solution is 4.61 %
