Question

* 3.65 gm of Hol are dissolved in a lit of solutionFind
molarity of the solution?
​

Answer 1

Answer:

Answer:

We know, Molarity of a solution is the no. of moles of solute present in 1 L of solution.

Here,

Mass of solute (HCl) = 3.65 g

and molar mass of HCl = 1 + 35.5 = 36.5 units

so,

no. of moles of HCl = given mass/molar mass = 3.65/36.5 = 0.1 mol

Now,

Molarity = 0.1/4 = 0.025 M
