Step 1: Calculate the total moles of solute in solution A
Moles of A = Molarity of A × Volume of A (in liters)
Moles of A = 1.3 mol/L × 0.1 L = 0.13 mol
Moles of A = Molarity of A × Volume of A (in liters)
Moles of A = 1.3 mol/L × 0.1 L = 0.13 mol
Step 2: Calculate the total moles of solute in solution B
Moles of B = Molarity of B × Volume of B (in liters)
Moles of B = 0.8 mol/L × 0.5 L = 0.4 mol
Moles of B = Molarity of B × Volume of B (in liters)
Moles of B = 0.8 mol/L × 0.5 L = 0.4 mol
Step 3: Calculate the total moles of solute in the mixture
Total moles = Moles of A + Moles of B
Total moles = 0.13 mol + 0.4 mol = 0.53 mol
Total moles = Moles of A + Moles of B
Total moles = 0.13 mol + 0.4 mol = 0.53 mol
Step 4: Calculate the total volume of the mixture
Total volume = Volume of A + Volume of B
Total volume = 0.1 L + 0.5 L = 0.6 L
Total volume = Volume of A + Volume of B
Total volume = 0.1 L + 0.5 L = 0.6 L
Step 5: Calculate the molarity of the mixture
Molarity of mixture = Total moles ÷ Total volume
Molarity of mixture = 0.53 mol ÷ 0.6 L = 0.883 mol/L
Molarity of mixture = Total moles ÷ Total volume
Molarity of mixture = 0.53 mol ÷ 0.6 L = 0.883 mol/L
Hence, The molarity of the resultant solution is 0.883 mol/L.
