Mass C₆H₈O₇ : 0.531484 g

Further explanation

Reaction

3NaHCO₃ (aq) + C₆H₈O₇ (aq) → 3 CO₂ (g) + 3 H₂O (l) + Na₃C₆H₅O₇ (aq)

MW NaHCO₃ : 84 g/mol

mass NaHCO₃ : 7.10² mg=0.7 g

mol NaHCO₃ :

[tex]\tt mol=\dfrac{0.7}{84}=0.0083[/tex]

mol C₆H₈O₇ :

[tex]\tt \dfrac{1}{3}\times 0.0083=0.00277[/tex]

MW C₆H₈O₇ : 192 g/mol

mass C₆H₈O₇ :

[tex]\tt mass=0.00277\times 192=0.53184[/tex]
