Question

Find normality of 4.5g of (C2H2O4.2H2O) dissolved in 250ml solution

Answer 1

Answer:

molarity.

Explanation:

number of moles =

$\frac{mass}{molecular \: mass}$

$= \frac{4.5}{126}$

=0.0357 moles

molarity=

$\frac{number \: of \: moles}{dm {}^{3} \: of \: solution }$

=

$\frac{0.0357}{0.25}$

=0.1428M
