A chemist has m gm of salt water that is m percent salty so how many gram of salt must be added to make a solution that is 2m percent salty?
2m-m=m more grams he needs
What is the molarity of a strong acid solution with a pH of 2?

Salt and water combine to make a solution .
How can you make solution of 2M of 800 ml from 5M solution?
In order to have a 2M solution is means that you have 2 moles for every 1 liter. Because you only want to make 800mL of this solution you only need (0.8*2) moles of or 1.6 moles of the compound in your solution. This 1.6 moles is coming from your 5M solution. So how much 5M do you need to take out to have 1.6 moles. A 5 molar solution has 5 moles for every liter, since you only need 1.6 moles of it that you need(1.6/5) liters of the solution or 0.32 liters (320 mL). Calculations done. So your going to take 320 mL of the 5M solution and put it into an 800mL volumetric flask and add water up to the line, or to be more exact, add exactly 460 mL of water in order to dilute the solution from 5M to 800mL of 2M solution.
Does salt and water make a compound?
no they do not they make a solution
How many grams of salt must be dissolved in water to make two liters of a two mole salt solution?
A 2M NaCl solution contains approximately 58.5g of salt. So to make two liters of a 2M solutions you would need 117g of salt dissolved in 2 liters of water.
What is the concentrate of 2M NaCl?
2M NaCl is a equivalent to a solution with 116,88 g NaCl in 1 L water.

How do you make a 0.1N tributylamine solution?
This compound is not soluble in water.
A chemist has m gm of salt water that is m percent salty so how many gram of salt must be added to make a solution that is 2m percent salty?
2m-m=m more grams he needs
What is the root of 2m plus 7 equals 8 plus m?
We're not sure what the question means by "root". It may be what's usuallyreferred to as the "solution" of the equation ... the number that 'm' must be inorder to make the equation a true statement. Here's how to find the 'solution':2m + 7 = 8 + mSubtract 7 from each side:2m = 1 + mSubtract 'm' from each side:m = 1
How would you prepare 30mL of a 5M NaCl solution from a 2M NaCl stock solution?
You have to evaporate (by open boiling) 45 mL of the 75 mL 2M NaCl solution thus reducing the volume to 30 mL 5M NaCl.
