How much methanol needed to make 100 ppm solution in 100ml water?
100ppm means, you need 100mg in 1oooml. Thus, for 100ml solution, you will need 10mg of methanol to make 100ppm solution.
How do you make a 10 percent Clorox solution?
10% = 10 parts in 100 or 1 in 10 parts. So if you make a solution, you need to make sure that whatever the amount of Clorox you use, the total amount of solution is 10 times larger. How to do this accurately depends on the measuring equipment you have available and the amount of solution you need to make.
If you are given 5 gL of stock solution to make 15 ml of 2.3 gL fructose solution how many L of the stock solution is needed to make the fructose solution?
You need 6,9 mL stock solution.
How many g of KCl do you need to make 2.5 L of a 10 weight volume solution?
For a 10 % solution you need 250 g KCl.
How many grams of KCl would you need to make 250 ml of a 5 M solution?
MW 74.5, 1M solution requires 74.5g in 1L, 5M solution requires 74.5x5 = 372.5g in 1 L. You would need 93.1g KCL to make 250mL 5M solution
What do you need to do to a concetrated solution to make it weaker?
Dilute it (add water).
How many grams of NaCl would you use to make 100ml of a 4M solution?
The Molecular Weight of NaCl = 58.5 So to make 1L of 4M NaCl solution you need 4*58.5=234g of NaCl So to make 100mL of the above solution you need 23.4 grams of NaCl
How many mg of salt do you need to make a salt solution of 3 ml if you need 1 gm of salt to make a solution of 2 ml?
Proportionally you will need 1 and 1/2 mg of salt.
How many grams sugar need to be added in a 100mL water to make a 10 sugar solution?
To make a 10% sugar solution you need to dissolve 10 grams of sugar and bring the volume up to 100 ml
When A chemist has one solution that is 80 acid and another solution that is 30 acid. How much of the first (80) solution is needed to make a 400 L solution that is 62 acid?
You need 256 litres.
How do you make a 2.5 percent acetic acid solution from a 33 percent solution?
so it is 33% already. You need to dilute every 33ml with 30.5ml solvent and adding 2.5ml of the solution. Feel free to message if you need further explaining
How many grams of KCl need to make 1000 ppm solution?
That completely depends on how much solution you need to end up with.If the solution is to be 1,000 ppm by weight (or mass), then you add 1 gramof KCl to each liter of water.
