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.
Another 12.625 gallons of water!
4 litres
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.
50 gallons of water!
360' gallons of water!!!!!!!
Saltwater is a solution because you can get fresh water and some salt and mix it and then you get saltwater.
1.2 gallons
From your question it is impossible to tell. A salt-water solution can be unsaturated or saturated depending on how much salt was added.
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.
What is saltwater...saltwater is just water and added salt.
This is a solution of sodium chloride (NaCl) in water.
In a basic saltwater solution, the water molecules would be the solvent and the salt molecules would be the solute.
freeze the saltwater solution
Salt water is a homogeneous solution, and a mixture.
yes because salt and water make saltwater in a solution.
You need 17 gallons for a 15% volume/volume mixture.
2 gallons.
