If it is 5 molar: 5 moles per liter, then you start with 5 moles of salt. You will always have 5 moles of salt, but it is spread among a bigger volume.
So you want it to be 2 moles per liter, so the amount of salt is 2*V, but we know that there are 5 moles, so we have 2*V = 5, and V = 5/2 = 2.5 Liters. Since we started with 1 liter, we must add 1.5 liters.
30 liters of a 10 % solution of fertilizer has .1(30) = 3 liters of fertilizer 1 liter of 30% solution has .3 liter of fertilizer 10 liters of 30% solution has 3 liters of fertilizer so, the chemist needs 10 liters of the 30% solution and 20 liters of water to make 30 liters of a 10% solution.
12*(90%)=10.8=X*.25 10.8/.25=X=43.2 43.2-12=31.2 31.2 grams of water must be added
Approx 1.86 gallons.
7 liters of a 20% acid solution consists of 1.4 liters of acid (20% of the total volume) mixed with 5.6 liters of water (80% of the total volume). The amount of acid isn't going to change in the new solution. You are just going to add enough water to make it a 10% solution instead of a 20% solution. So it will be more dilute. That means that 1.4 liters of acid will represent 1/10 of the volume of the new solution. So the total volume of the new solution will be 10 x 1.4 or 14 liters. The amount of water in the new solution will be 14 - 1.4 = 12.6 liters. That is a difference of 12.6 - 5.6 = 7 liters from the amount of water you started with. So you need to add 7 liters of water to the original 20% solution to make it a 10% solution. This makes sense because if you double the amount of the mixture from 7 liters to 14 liters and the amount of acid is unchanged, the solution will be half as strong.
You have 6 litres of alcohol in 24 litres of water You need to add x litres to make 6 equal to 15% of 30 + x. 6 is 15% of 40, so x = 10
A saline solution is formed.
The chemical and physical properties are changed.
This is an isotonic saline solution; 9 g/L sodium chloride solution in water with added glucose.
Not exactly. Saline solution is sterilized and is a dilution of sodium chloride (NaCl) - meaning that the NaCl is dissolved in deionized water. The solution is 9 grams of sodium chloride (NaCl) dissolved in 1 liter of water.
saline solution is salted water with 0.85% of salt
Saline is a homogenous solution of salt in water.
Saline solution is a mixture of salt and water.
Not sure what you are using saline solution for but i would say that saline solution is steril and water is not.
saline solution
The answer is 9 g NaCl.
There is 1 gallon of 10% solution...There is 0% saline in water...The equation is (0.1)(1) + 0x = 0.02 (x+1)...Answer is: 4 gallons. Hope I helped!!:)
No, saline is water H2O with sodium chloride NaCl, and water is just H2O
