Final answer:
The original concentration of Ca(OH)2 is found by dividing the number of moles by the original volume of the solution in liters. If the moles are 0.00195 and the volume is 0.04402 L, the concentration is 0.0443 M.
Step-by-step explanation:
To calculate the original concentration of Ca(OH)2 using its original volume, you would apply the formula for concentration (Molarity = Moles of solute / Volume of solution in liters). Given the number of moles of Ca(OH)2 and the original volume in liters, the calculation is straightforward.
For instance, if the moles of Ca(OH)2 were found to be 0.00195 from a titration reaction with HNO3, and the original volume was 0.04402 L, the original concentration would be:
Molarity (M) = Moles of Ca(OH)2 / Volume of solution
Molarity (M) = 0.00195 mol / 0.04402 L
Molarity (M) = 0.0443 M
