Answer 2

Calculating the Mass of Salt for a 65% Solution

To calculate the mass of salt needed to obtain a 270g 65% solution, we can use the formula:

Mass of salt = (Percentage / 100) * Total mass of solution

Substituting the given values: Mass of salt = (65 / 100) * 270g

Calculating the mass of salt: Mass of salt = 0.65 * 270g Mass of salt = 175.5g

So, the mass of salt needed to obtain a 270g 65% solution is 175.5 grams.
