What is the mass percent of solute When, 4.12 grams is dissolved in 100 .0 gram of water.

The mass percent of solute can be calculated using the following formula:

Mass percent of solute = (mass of solute / mass of solution) x 100%

Substituting the given values,

Mass percent of solute = (4.12 g / 100.0 g) x 100% = 4.12%

Therefore, the mass percent of solute when 4.12 grams is dissolved in 100.0 grams of water is 4.12%.

To calculate the mass percent of solute, you need to divide the mass of the solute by the mass of the solution (solute + solvent), and then multiply by 100.

1. Calculate the mass of the solute:

mass of solute = 4.12 grams

2. Calculate the mass of the solvent:

mass of solvent = 100.0 grams of water

3. Calculate the mass of the solution (solute + solvent):

mass of solution = mass of solute + mass of solvent

mass of solution = 4.12 grams + 100.0 grams

4. Calculate the mass percent of solute:

mass percent of solute = (mass of solute / mass of solution) x 100

mass percent of solute = (4.12 grams / (4.12 grams + 100.0 grams)) x 100

mass percent of solute = (4.12 grams / 104.12 grams) x 100

mass percent of solute = 0.03961 x 100

mass percent of solute = 3.961%

Therefore, the mass percent of solute when 4.12 grams is dissolved in 100.0 grams of water is approximately 3.961%.
