**Problem Statement:**Calculate the sodium ion concentration when 60.0 mL of 2.0 M sodium carbonate is added to 40.0 mL of 1.3 M sodium bicarbonate. Assume that the volumes are additive.**Input Area:**Concentration = [_________] M**Options:**- Submit Answer- Try Another Version6 item attempts remaining---This is an educational exercise for calculating the final concentration of sodium ions when two solutions are mixed together. Two solutions are being mixed: sodium carbonate ($\text{Na}_2\text{CO}_3$) and sodium bicarbonate ($\text{NaHCO}_3$).**Steps to Solve:**1. **Calculate the moles of sodium ions in each solution:** - Sodium carbonate provides two sodium ions per formula unit. - Sodium bicarbonate provides one sodium ion per formula unit.2. **Find the total volume after mixing:** - Add the volumes of the two solutions.3. **Use the formula for concentration:** - \[ C = \frac{\text{Total moles of sodium ions}}{\text{Total volume in liters}} \]By solving this problem, students can practice calculating molarity in mixed solutions, reinforcing concepts of stoichiometry and solution chemistry.

Given that: Concentration of sodium carbonate = 2.0M Volume = 60.0ml = 60.0ml×1L/1000ml = 0.060L Molarity = moles ÷ volume Moles of Na2CO3 = (2.0mol/L)×0.060L = 0.12mol (2mol Na+/1mol Na2CO3)×0.12mol Na2CO3 = 0.24mol Na+ Simillarly Moles of sodium bicarbonate (NaHCO3) = (1.3mol/L)×0.040L = 0.052mol 0.052mol NaHCO3 has 0.052mol Na+ ions Total volume after mixing of both solution = 60.0ml+40.0ml = 100.0ml = 0.1L Total moles of Na+ in mixture= 0.24mol+0.052mol = 0.292 mol Concentration of sodium ion = 0.292mol÷0.1L = 2.92mol/L Concentration = 2.92 M

Percent acetic acid in the vinegar Hints: For #4, The amount of NaOH used is the difference between the starting buret value and the ending buret value. For #6, Once you calculate the amount of sodium hydroxide used, multiple that value by the concentration of NaOH in the NaOH solution. For #7, Multiply the value obtained in number 6 by the number 1.5. Remember, we learned that every 1 gram of NaOH neutralizes 1.5 grams of acetic acid.
