Answer:
0.113 M
Explanation:
The reaction that takes place is:
- NaHCO₃ + HCl →NaCl + CO₂ + H₂O
First we convert 0.3967 g of NaHCO₃ into moles, using its molar mass:
- 0.3967 g ÷ 84 g/mol = 4.72x10⁻³ mol NaHCO₃
As 1 mol of NaHCO₃ reacts with 1 mol of HCl, in 41.77 mL of the HCl solution there were 4.72x10⁻³ moles of HCl.
With the <em>calculated number of moles and the given volume </em>we <u>calculate the concentration of the solution</u>:
- Converting 41.77 mL ⇒ 41.77 mL / 1000 = 0.04177 L
- Concentration = 4.72x10⁻³ mol / 0.04177 L = 0.113 M
