Formulae:
(m/v) % = [mass of solute (g) / volume of solution (mL)] x 100

ppm (m/v) = [mass of solute (g) / volume of solution (mL)] x 106

You can either leave it as it is 1% m/V or add in parentheses (mass-volume percentage).

or mass-volume percent... depending on how you want to phrase it,,,

1 % m/V = 1 gram of solute in 100 mL of solvent.

The solvent here being water, of course.

The solute is isopropylamine [ (CH_3)_CH2NH2 ] with the whole solution buffered between the specified pH values (basic pH values... as isopropylamine itself is a basic substance).

--------------------------------------------------

Should be (CH_3)_2_CH_2NH_2

--------------------------------------------------
Note added at 5 hrs 24 mins (2005-07-17 01:25:06 GMT)
--------------------------------------------------

Actually the formula should be:

[ [ (CH3)_2CH ]_2 ]-NH

--------------------------------------------------

Two isopropyl groups attached to the amine moiiety (-NH here). We can start with ammonia (NH3) and then replace two hydrogens by two isopropyl groups to get isopropylamine.
