Amount of HCl in 150ml of 1.6M HCl `= (1.6/1000)xx150 =0.24`
Now we need to take 0.24mol of HCl from 8M HCl solution and dilute it with distilled water until the volume of the total mix become 150ml.
Amount of 8M HCl needed` = (1000/8)xx0.24 =30 ml`
So we need to take 30ml of 8M HCl and add 120ml of distilled water to make it 150ml.So then we have 150ml of 1.6M HCl solution.
