prepare some 0.1 HCl by diluting the appropriate volume of stock 'conc' HCl to 1L. The stock acid is 37.4% HCl by weight and has a density of 1.19g/mL . Measure out the required volume with a graduated clyinder

Answer 1

0.1 WHAT HCl? 0.1M, 0.1N, 0.1m, 0.1% w/w 0.1% w/v.
I will assume 0.1 M.
I would calculate the molarity of the stock HCl first.
1.19 g/mL x 1000 mL x 0.374 x (1 mol/36.5) = ?M
Then use the dilution formula which is
M1V1 = M2V2
