Question

Given below are two statements: one is labelled as Assertion A and the other is labelled as Reason R.

Assertion A: $3.1500 g$ of hydrated oxalic acid dissolved in water to make $250.0 m L$ solution will result in $0.1 M$ oxalic acid solution.

Reason R: Molar mass of hydrated oxalic acid is $126 g m o l^{- 1}$ .

In the light of the above statements, choose the correct answer from the options given below:

TestHub · Accepted Answer

Molarity ( M ) = wt mwt × V × 1000 Using this formula, we can calculate the molarity of the oxalic acid solution as follows: Mass of hydrated oxalic acid = 3 . 1500 g Molar mass of hydrated oxalic acid ( H 2 C 2 O 4 · 2 H 2 O ) = 126 . 064 g / mol Volume of the solution = 250 . 0 mL Molarity ( M ) = 3 . 15 × 1000 126 × 250 = 0 . 10 So both assertion land reason are correct.
