Question

a sample of Sodium Hydroxide when 0.48 gram is dissolved in water and the solution is made up of 250 4.0 cm cube in volumetric flask what is the molarity of the
resulting solution​

Answer 1

Answer: M = 0.2

Explanation:

Weight of solute (NaOH) = 0.40

Molar mass of solute (NaOH) = 40g

Now, 1L = 1000cm^3 = 1000ml

50cm^3 = 50ml

Volume of solution = 50 ml

Molarity = Wb x 1000/ Mb x V

0.40 x 1000/ 40 x 50

M = 0.2
