Question

Please help me regarding this question​

Answer 1

Answer:

Hey mate,

Your answer will be

0.2M

Explanation:

Molecular weight of oxalic axid =

$12 \times 2 + 2 + 16 \times 4 = 90$

and we know that

$mole(n) = \frac{weight}{molecular \: weight}$

$n = \frac{1.8}{90} \\ n = 0.02$

$molarity = \frac{mole \: of \: solute}{volume \: of \: solution \: (litre)}$

$molarity = \frac{0.02 \times 1000}{200}$

$molarity = 0.2$

Hence molarity is 0.2 M

Hope this will help uh!
