Question

2.3 g of C,H,OH (mol. wt. 46) are dissolved in
water to form 500 mL solution. The molarity of the
solution is-​

Answer 1

Explanation:

2.3/46 *1000/500

In this way u calculate molarity

Answer 2

Given:

Molecular weight = 46

weight of solute = 2.3 g

volume of solution = 500 mL

Find:

Molarity of the solution

Solution:

Molarity = $\frac{W2}{M2}$×$\frac{1000}{Volume\ of\ solution\ in\ ml}$

(Where W2 is the weight of solute and M2 is the molecular weight)

              =$\frac{2.3}{46}$×$\frac{1000}{500}$

              = 0.1 molar solution

Hence the molarity of the given solution is 0.1 M
