Answer : The mass of
prepared can be 3.18 grams.
Explanation : Given,
Mass of NaOH = 2.40 g
Molar mass of NaOH = 40 g/mole
Molar mass of
= 106 g/mole
First we have to calculate the moles of
.
Now we have to calculate the moles of
.
The balanced chemical reaction is,
From the balanced reaction we conclude that,
As, 2 moles of
react to give 1 mole of ![Na_2CO_3](/tpl/images/1118/2345/1e92a.png)
So, 0.06 moles of
react to give
of ![Na_2CO_3](/tpl/images/1118/2345/1e92a.png)
Now we have to calculate the mass of
.
Therefore, the mass of
prepared can be 3.18 grams.
