solvent and solute
100ppm means, you need 100mg in 1oooml. Thus, for 100ml solution, you will need 10mg of methanol to make 100ppm 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.
You need 6,9 mL stock solution.
For a 10 % solution you need 250 g KCl.
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
Dilute it (add water).
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
Proportionally you will need 1 and 1/2 mg of salt.
To make a 10% sugar solution you need to dissolve 10 grams of sugar and bring the volume up to 100 ml
You need 256 litres.
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
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.
