Eq. wt. of oxalic acid =( textMol.wt/ textBasicity) =( textMol.wt/2)=(126/2)=63 Weight of oxalic acid required to prepare 1000 mL (N/10) solution =6.3 g

Q. What weight of oxalic acid $(H_{2} C_{2} O_{4} 2 H_{2} O)$ is required to prepare 1,000 mL of N/10 solution?

9.0 g

12.6 g

6.3 g

4.5 g

Eq. wt. of oxalic acid
$= \frac{Mol.wt}{Basicity} = \frac{Mol.wt}{2} = \frac{126}{2} = 63$
Weight of oxalic acid required to prepare 1000 mL
$\frac{N}{10}$ solution $= 6.3 g$
