Answer:
Number of produced moles of carbondioxide is 0.113 mol.
Explanation:
Excess of sulphuric acid is present.And the sodium carbonate is completely consumed.
Molar mass of sodium carbonate = 105.99g/mol
Given mass of sodium carbonate =12 g/mol
[tex]Number\,of\,moles=\frac{Given\,mass}{Molar\,mass}[/tex]
[tex]Number\,of\,moles=\frac{12}{105.99}=0.113mol[/tex]
one mole of sodium carbonate produce one mole of carbondioxide.
0.113 mole of sodium carbonate produce 0.113 mole of carbondioxide.
[tex]Mass\,of\,CO_{2}produced=Moles\times Molar\,mass[/tex]
[tex]=0.113\times 44g/mol=4.98g[/tex]
Therefore, 0.113 mol of carbondioxide produced in flask 7.
