Thank you for the help,
I just did not know where to look. I know now, even it is a little confusing, since there is no clear opinion.
To prepare a 1 mol solution of say NaOH (1 Mole = 39.9971g)
do I add this (1 Mole = 39.9971g) to 1 liter of water, or do I add 1 Liter of water to 1 Mole = 39.9971g of NaOH???
And How do I prepare 2.5 N H2SO4??? Shulgin wrote 2,5 N not M. so is it 1.25 mol H2SO4 adding to H2O till I have 1 Liter??
This would be 122.59875 Gramm of H2SO4 in a cylinder and I add Water till I have 1 liter??
Thank you...
And thank you Calcium, for the tip, very encouraging, especially for a newbee. Spitball was equally arrogant, look where he is now...
