Answer : The mass of sodium carbonate added to neutralize must be,
Explanation :
First we have to calculate the moles of .
Given:
Molar mass of = 98 g/mole
Mass of =
Conversion used : (1 kg = 1000 g)
Now put all the given values in the above expression, we get:
The moles of is,
Now we have to calculate the moles of
The balanced neutralization reaction is:
From the balanced chemical reaction we conclude that,
As, 1 mole of neutralizes 1 mole of
So, of
neutralizes
Now we have to calculate the mass of
Molar mass of = 106 g/mole
Thus, the mass of sodium carbonate added to neutralize must be,
