Answer:
The mass of 50% solution of required to react with
of
measured is
.
Explanation:
Given,
The mass of =
The mass of =?
As we know,
- The reaction of
with
follows in the way given below:
From this reaction, we can say that of
required to react with
of
.
Now,
- The number of moles of
, n =
- Molar mass of
, M =
Therefore,
- The mass of
= n × M =
=
