Lee dissolved 8 grams of a salt in a certain amount of water to obtain 608 grams of salt solution. what was the mass of the water used to make the solution?

600 g of the water was used to make the salt solution.

Explanation:

In a salt solution ,salt is present as a solute and water as a solvent.

Mass of salt present in the solution = 8 g

Mass of the salt solution = 608 g

Solution = Solvent + Solute

608 g = solvent + 8 g

Mass of water = 608 g - 8 g= 600 g

600 g of the water was used to make the salt solution.

2h2o2--> 2h2o + o2

this reaction is of the spontaneous decomposition of hydrogen peroxide down into water and oxygen.

add 2 molecules of hydrogen peroxide and 2 molecules of water. since oxygen is naturally diatomic, the total number of atoms of each element is now the same on both sides of the equation so it is balanced.

this may not be entirely correct but let me know.
