I just want to solve a stupid debate about molarity.
Solute = benzyl alcohol
Solute density at 20oC= 1.0453g/mL
Solute molecular mass = 108.13g/mol
Needed concentration = 0.25M
Needed volume = 10mL
Solvent = CCl4
mol solute needed = 0.25mol/L x 0.01L = 0.0025mol
A) Mass solvent needed = fill up to 10mL
B) Mass solvent needed = 10mL x 1.0453g/mL = 10.4530g
This means that 10mL mark will be exceeded.
What is the correct method? If I could get the person to post you a chocolate bar for winning this bet, I would.
