Question

2M of oxalic acid in 1L of solution . find mass by using formula of molarity​

Answer 1

Answer:

3.15g

Explanation:

For hydrated oxalic acid, (COOH)  

2

​  

.2H  

2

​  

O, molar mass is 126 g/mol.

Equivalent weight =  

2

M

​  

=63

Meq. of oxalic acid =500×0.1=50

E×1000

w

​  

=50

w=  

2

126

​  

×50×1000=3.15 g

Hence, mass of oxalic acid required is 3.15 g.
