How many gallons of pure water must be added to 10 gallons of 30 saltwater to make a solution that is 25 salt water?
I take it that there should be percentage signs in this question. How many gallons of pure water must be added to 10 gallons of 30% saltwater to make a solution that is 25% saltwater?" If 30% of the 10 gallons is saltwater that means that 3 gallons are saltwater. As only pure water will be added, we need to find out how many gallons = 100% if 3 gallons = 25%. The relationship of 100 to 25 is 4 : 1, so there will need to be a total of (3 x 4) gallons at the end of the operation. As 3 x 4 = 12, and as we started with 10 gallons, that means that we need to add 2 gallons of pure water.

How much of a 50 percent solution should be added to 1 liter to make a 25 percent solution?
Mix this 50% solution in equal quantities with water(?) to halve it's strength. So use 1 litre of the 50% solution and 1 litre of water of that's what you are diluting it with.

Is saltwater a solution or solute?
Saltwater is a solution because you can get fresh water and some salt and mix it and then you get saltwater.
How A cork is floating in a saltwater solution As more salt is added to the water to increase its density what happens to the cork?
As more salt is added to the saltwater solution, the density of the water increases. Eventually, the density of the saltwater solution becomes greater than the density of the cork, causing the cork to sink. This is because denser objects tend to sink in less dense fluids.
What is a solute and solevent in a saltwater solution?
In a basic saltwater solution, the water molecules would be the solvent and the salt molecules would be the solute.
Is saltwater solution saturated or unsaturated?
From your question it is impossible to tell. A salt-water solution can be unsaturated or saturated depending on how much salt was added.
Is water a saltwater solution?
No. Pure water is a compound, which is a pure substance. A saltwater solution is a mixture of water and salt, and is not a pure substance.
