The answer should be 6.94

The grams of bicarbonate that will produce 40 ml of CO2 is 0.10007 grams

The dissociation of bicarbonate ion to CO2 can be expressed as:

[tex]\mathbf{HCO^-_3 + H^+ \to H_2CO_3 \rightarrow CO_2 + H_2O}[/tex]

Given that:

  • volume = 40 mL = 0.040 L

At standard conditions:

  • Pressure = 1 atm
  • Temperature = 298 K

Using the ideal gas equation;

the number of moles of CO2 can be computed as:

  • PV = nRT
  • n = PV/RT

[tex]\mathbf{n = \dfrac{1 \ atm \times 0.04 \ L }{0.0821 \ L.atm/mol.K \times 298 K}}[/tex]

n = 0.00164  moles

The number of grams of bicarbonate produced from 40 mL of CO2 will be:

= 0.00164  moles × 61.0168 g/mol (molar mass of bicarbonate ion)

= 0.10007 grams of bicarbonate ion

Therefore, we can conclude that the grams of bicarbonate that will produce 40 ml of CO2 is 0.10007 grams.
