Calculate the mass of sodium bromide dihydrate is required to prepare 250 mL of a 0.00600 M solution

The mass of sodium bromide dihydrate is 0.208 grams

Explanation:

Molarity of a solution is defined as the number of moles of solute dissolved per liter of the solution.

where,

n = moles of solute

= volume of solution in ml  = 250 ml

moles of =

Now put all the given values in the formula of molality, we get

Therefore, the mass of sodium bromide dihydrate is 0.208 grams

the reaction mixture contains some ammonia, plus a lot of unreacted nitrogen and hydrogen. the mixture is cooled and compressed, causing the ammonia gas to condense into a liquid. the liquefied ammonia is separated and removed. the unreacted nitrogen and hydrogen are then recycled back into the reactor .

practical process described pest part of scientific investigation.

because practical knowledge is powerful then therotical knowledge.
