1 M, 2.5 litre NaOH solution is mixed with another 0.5 M, 3 litre NaOH...
From molarity equation M1V1 + M2V2 = MV
1× 2.5 + 0.5 × 3 = M × 5.5
1× 2.5 + 0.5 × 3 = M × 5.5

1 M, 2.5 litre NaOH solution is mixed with another 0.5 M, 3 litre NaOH...
M = M1V1+M2V2 / V1+V2. M = 1*2.5+0.5*3 / 2.5+3.
M = 4 / 5.5. M = 0.73
M = 4 / 5.5. M = 0.73

1 M, 2.5 litre NaOH solution is mixed with another 0.5 M, 3 litre NaOH...
Given Data:
- Molarity of first solution (M1) = 1 M
- Volume of first solution (V1) = 2.5 L
- Molarity of second solution (M2) = 0.5 M
- Volume of second solution (V2) = 3 L
Calculation:
Step 1: Calculate total moles of NaOH in each solution
- Moles of NaOH in first solution = M1 x V1 = 1 M x 2.5 L = 2.5 moles
- Moles of NaOH in second solution = M2 x V2 = 0.5 M x 3 L = 1.5 moles
Step 2: Calculate total volume of resultant solution
- Total volume of resultant solution = V1 + V2 = 2.5 L + 3 L = 5.5 L
Step 3: Calculate molarity of resultant solution
- Molarity of resultant solution = (Total moles of NaOH) / (Total volume of resultant solution)
- Total moles of NaOH = Moles of NaOH in first solution + Moles of NaOH in second solution = 2.5 moles + 1.5 moles = 4 moles
- Molarity of resultant solution = 4 moles / 5.5 L = 0.73 M
Therefore, the molarity of the resultant solution after mixing the two NaOH solutions is 0.73 M, which corresponds to option 'c'.
- Molarity of first solution (M1) = 1 M
- Volume of first solution (V1) = 2.5 L
- Molarity of second solution (M2) = 0.5 M
- Volume of second solution (V2) = 3 L
Calculation:
Step 1: Calculate total moles of NaOH in each solution
- Moles of NaOH in first solution = M1 x V1 = 1 M x 2.5 L = 2.5 moles
- Moles of NaOH in second solution = M2 x V2 = 0.5 M x 3 L = 1.5 moles
Step 2: Calculate total volume of resultant solution
- Total volume of resultant solution = V1 + V2 = 2.5 L + 3 L = 5.5 L
Step 3: Calculate molarity of resultant solution
- Molarity of resultant solution = (Total moles of NaOH) / (Total volume of resultant solution)
- Total moles of NaOH = Moles of NaOH in first solution + Moles of NaOH in second solution = 2.5 moles + 1.5 moles = 4 moles
- Molarity of resultant solution = 4 moles / 5.5 L = 0.73 M
Therefore, the molarity of the resultant solution after mixing the two NaOH solutions is 0.73 M, which corresponds to option 'c'.
