Hi there everyone.

I am facing a problem with Chemistry.

Here is the situation:

I have 1.5 cubic decimetres of sulphuric acid. There is nothing written on the label, except for the name of the acid and 98 g/mol.

With those given information, can I find out the molarity/concentration of the acid?

Your help is very much appreciated!

Thank you...

number of mole= mv/1000

u Got number of mole, u got volume.

Do MOLAR MASS and NUMBER OF MOLES mean the same thing???

Added on March 2, 2011, 9:58 pmWhat I have is molar mass (g/mol) and not number of moles...

The formula mv/1000 will give the answer in mol and not g/mol.

Omg...pening pening...

check out the Form 4 Chapter 7 Text Book
=].. There's a formula on how to change g/mol to no of mole ( if im not wrong )..

no.... LOL

Courtesy of my fiancee,
Volume = 1.5 dm^3
number of mole change from the 98 g/mol...

then u need find m from the formula mv/1000.

Sorry...but I do not understand your explanations.

Can you please provide an example?

Thank you...

subtitute using the equation only...

Please verify if this is correct...

Num of mole = 98, volume = 1.5 dm3.

So molarity = mol/v = 65.333 mol/dm3.

lol... mol is not 98....

use the value of 98 to change to mol....

Ohh....

How to change it to mol?

insufficient information......
need to know the density of the solution or the mass of the solution

omg. this is very simple.

I suggest u get a reference book like sasbadi/success/focus.

Those are good at my times.

Formula, Molarity = Concentration/Volume (in dm^3)

I know it is simple...

That's Form 4 Chemistry, for god's sake...

just need the mass of the solution. coz u take the mass/molar mass(96g) = mole then u take the mole/volume(1.5dm^3)
or just take the mass/volume(1.5dm^3)

Thanks a lot!!!
