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 electrical  conductivity  of asolution  of an electrolyte is measured by determining the resistance of thesolution  between two flat or cylindrical electrodes separated by a fixed distance.
