Calculate the morality of a solution made by mixing 250ml of 0.75M H2SO4 with 400ml of 2.5MH2SO4
1.8 M
To calculate the morality of a solution made by mixing two different solutions, we can use the principle of the conservation of moles. The morality (M) is defined as the number of moles of solute divided by the volume of the solution in liters.
First, let's calculate the number of moles of H2SO4 in each solution:
Moles of solute (H2SO4) = Molarity (M) x Volume (L)
For the first solution:
Moles of H2SO4 = 0.75 M x 0.250 L (since 250 ml = 0.250 L)
For the second solution:
Moles of H2SO4 = 2.5 M x 0.400 L (since 400 ml = 0.400 L)
Now, let's add the moles of H2SO4 from both solutions together:
Total moles of H2SO4 = Moles of H2SO4 from the first solution + Moles of H2SO4 from the second solution
Total moles of H2SO4 = (0.75 M x 0.250 L) + (2.5 M x 0.400 L)
Now, we need to calculate the total volume of the solution:
Total volume of solution = Volume of the first solution + Volume of the second solution
Total volume of solution = 0.250 L + 0.400 L
Finally, we can calculate the morality of the solution:
Morality (M) = Total moles of H2SO4 / Total volume of solution
Morality (M) = (0.75 M x 0.250 L + 2.5 M x 0.400 L) / (0.250 L + 0.400 L)
Calculating the numerical value of this expression will give you the morality of the solution made by mixing the two given solutions.
