If 25 ml of 0.11 M sucrose is added to 10 ml of 0.52 M sucrose, what will be the resulting Molarity?
millimoles soln 1 = mL x M = ?
mmoles soln 2 = mL x M = ?
M final soln = (mmoles 1 + mmoles 2)/total volume in mL.
0.22M
To find the resulting molarity, you need to calculate the total moles of sucrose and then divide by the total volume.
Step 1: Calculate the moles of sucrose in each solution.
Moles = Concentration (M) x Volume (L)
For the first solution:
Moles = 0.11 M x 0.025 L = 0.00275 moles
For the second solution:
Moles = 0.52 M x 0.010 L = 0.0052 moles
Step 2: Add the moles from both solutions to get the total moles.
Total moles = 0.00275 moles + 0.0052 moles = 0.00795 moles
Step 3: Add the volumes of both solutions to get the total volume.
Total volume = 0.025 L + 0.010 L = 0.035 L
Step 4: Calculate the resulting molarity by dividing the total moles by the total volume.
Resulting Molarity = Total moles / Total volume = 0.00795 moles / 0.035 L
Calculating this division, the resulting molarity will be approximately 0.227 M.
To find the resulting molarity when two solutions are mixed, we can use the formula:
(M1)(V1) + (M2)(V2) = (M3)(V3)
Where:
M1 = molarity of the first solution
V1 = volume of the first solution
M2 = molarity of the second solution
V2 = volume of the second solution
M3 = resulting molarity
V3 = resulting volume
In this case:
M1 = 0.11 M (molarity of the first solution)
V1 = 25 ml (volume of the first solution)
M2 = 0.52 M (molarity of the second solution)
V2 = 10 ml (volume of the second solution)
Let's substitute the values into the formula:
(0.11 M)(25 ml) + (0.52 M)(10 ml) = (M3)(V3)
(2.75 mol) + (5.2 mol) = (M3)(V3)
7.95 mol = (M3)(V3)
Since we don't have the volume of the resulting solution, we cannot directly calculate the resulting molarity. We need to know the total volume of the mixed solution.
If you provide the volume of the resulting solution, I can help you calculate the resulting molarity using the equation (7.95 mol)/(V3).
