i just wanna ask, when u r given concentration in g/dm^3 how can u change it into moles/dm^3 ?

multiply the denominator by the Mr of the that substance and YOu will have mol per dm Cube....i just wanna ask, when u r given concentration in g/dm^3 how can u change it into moles/dm^3 ?
Ammonia turns damp red litmus paper blue.what's a chemical test for ammonia gas?
is that a chemical test?Ammonia turns damp red litmus paper blue.
Wats a chemical test??is that a chemical test?
do uk how to draw the straight line of neutralization on the graph? pls help meu just divide the mass by the molar mass of the substance to get the moles......so for example we are talkin about the concentration of HCl is let's say 3.65g/dm3 so u divide 3.65 by the Mr which is 36.5 and you get your conc as 0.1mol/dm3......hope you understood...
we haven't done that too, i understood the first graph but the second one not :/http://www.docbrown.info/page12/gifs/pHgraphnotes.gif

i got these from google...chek em out
but we havent done these sort of things at xul so i m not sure how to do it...sorry:/
can u have a look at nov/oct 11 u will see a graph where it says draw 2 lines which intersect do u have any i dea how to do that?yea same here i understood the first one but the second one is kinda complex...not for our level i think:/
We did that paper, and well wen u do it, the temp change you get, first increases and then decreases. So when you plot and draw you get One graph that goes up and another that comes down. U then extrapolate it and you get like a upside down V.can u have a look at nov/oct 11 u will see a graph where it says draw 2 lines which intersect do u have any i dea how to do that?
checked it.....zero idea:Scan u have a look at nov/oct 11 u will see a graph where it says draw 2 lines which intersect do u have any i dea how to do that?
