Answer : The mass of sodium carbonate added to neutralize must be,![6.54\times 10^3kg](/tpl/images/0514/0504/d48af.png)
Explanation :
First we have to calculate the moles of
.
Given:
Molar mass of
= 98 g/mole
Mass of
= ![6.05\times 10^3kg=6.05\times 10^6g](/tpl/images/0514/0504/bdfd0.png)
Conversion used : (1 kg = 1000 g)
Now put all the given values in the above expression, we get:
The moles of
is, ![6.17\times 10^4mol](/tpl/images/0514/0504/65091.png)
Now we have to calculate the moles of![Na_2CO_3](/tpl/images/0514/0504/1e92a.png)
The balanced neutralization reaction is:
From the balanced chemical reaction we conclude that,
As, 1 mole of
neutralizes 1 mole of ![Na_2CO_3](/tpl/images/0514/0504/1e92a.png)
So,
of
neutralizes
Now we have to calculate the mass of![Na_2CO_3](/tpl/images/0514/0504/1e92a.png)
Molar mass of
= 106 g/mole
Thus, the mass of sodium carbonate added to neutralize must be,![6.54\times 10^3kg](/tpl/images/0514/0504/d48af.png)
