To produce 4.00 l of a 250 mm solution of sodium hydroxide, how many grams of naoh must be dissolved?

Explanation:

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

where,

Molarity = 250mM =

n= moles of solute  

= volume of solution in ml = 4L = 4000 ml

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

Therefore, the of NaOH must be dissolved.

a electronegativity decreases beacuse the size of nucleus is bigger.
