What is the final concentration if 27.08 (MW: 36.46) dissolved in 55.51 ml?
In what units? molarity? 27.08 what? grams?
mol = grams/molar mass
Then M = mols/L solution.
I'm sorry I confused the questions

What is the final concentration if 64.36 grams of HCl (MW: 36.46) is dissolved in 8.54 ml of solution
Same procedure.
mols HCl = grams/molar mass
Then M = mols/L solution.
To determine the final concentration, you need to divide the number of moles of the solute by the volume of the solution.
Firstly, you need to calculate the number of moles of the solute (27.08 g). To do this, divide the mass of the solute by its molar mass:
moles of solute = mass of solute / molar mass
Given that the mass of the solute is 27.08 g and the molar mass is 36.46 g/mol, we can calculate the moles of solute:
moles of solute = 27.08 g / 36.46 g/mol
Next, you need to calculate the final concentration. To do this, divide the number of moles of the solute by the volume of the solution:
concentration = moles of solute / volume of solution
Given that the moles of solute is 27.08 g / 36.46 g/mol and the volume of the solution is 55.51 mL, we can calculate the concentration:
concentration = (27.08 g / 36.46 g/mol) / 55.51 mL
Make sure the volume is in the same units as the molar mass (mol).
By substituting the values into the equation, you can perform the calculations and get the final concentration.
