When an antacid tablet dissolves in water, the fizz is due to a reaction between sodium hydrogen carbonate (sodium bicarbonate, NaHCO3) and citric acid (H3C6H5O7). 3 NaHCO3(aq) H3C6H5O7(aq) 3 CO2(g) 3 H2O(l) Na3C6H5O7(aq) How many moles of Na3C6H5O7 can be produced if one tablet containing 0.0370 mol of NaHCO3 is dissolved

Respuesta :

Answer : The moles of [tex]Na_3C_6H_5O_7[/tex] produced can be, 0.0123 mole

Explanation : Given,

Moles of [tex]NaHCO_3[/tex] = 0.0370 mol

The given balanced chemical reaction is:

[tex]3NaHCO_3(aq)+H_3C_6H_5O_7(aq)\rightarrow 3CO_2(g)+3H_2O(l)+Na_3C_6H_5O_7(aq)[/tex]

From the balanced chemical reaction we conclude that,

As, 3 moles of [tex]NaHCO_3[/tex] react to give 1 mole of [tex]Na_3C_6H_5O_7[/tex]

So, 0.0370 moles of [tex]NaHCO_3[/tex] react to give [tex]\frac{0.0370}{3}\times 1=0.0123mole[/tex] of [tex]Na_3C_6H_5O_7[/tex]

Thus, the moles of [tex]Na_3C_6H_5O_7[/tex] produced can be, 0.0123 mole
