Molarity of sodium oxalate =(3.2 × 1000/134 × 500) M Na 2 C 2 O 4=0.04776

Q. A student prepared a standard solution of sodium oxalate by weighing $3.2 g$ of the dry anhydrous salt, dissolving it in distilled water and making the solution upto $500 m L$ . Molarity of the sodium oxalate solution is

0.04776

0.07446

0.06447

0,07644

Molarity of sodium oxalate $= \frac{3.2 \times 1000}{134 \times 500}$

$M_{N a_{2} C_{2} O_{4}} = 0.04776$
