lets find the Molarity of the 10 percent solution.
assume 1000g of solution, or 100gHCL, 900g H2O. moles HCl= 100/36.5=2.80 moles
now this solution has a density of 1.08, so the volume is 1000g/1.08g/ml= .917 liters
Molarity= 2.80/.917 =3.05M
you want to dilute it 3.05/.1=30.5times
which means one part original, 29.5 parts water.
What is one part? it is the volume desired of the .1M, divided by 30.5
twenty-nine point five parts is that one part multiplied by 29.5
Hello,
Please help me with this question!
Which dilution would turn 10% (by mass) HCl solution into 0.100 M HCl solution?
Density of 10% HCL = 1.08 g ml^-1
