how to make .008N SLS(sodium lauryl sulfate).
need to do tiration analysis

when i calculated i got .85g/lit pla show the calculation plzzzzzzzzzzzzz

What is molar mass of SLS? Or at least - do you know its formula? Or perhaps you are at least able to google it?

That may be not that easy to determine as lauryl sulphates are a mixture of alkyl sulphates. Sodium dodecyl sulphate on the other hand...

I thought lauryl sulfates were well defined. Laureth sulfates on the other hand....?

molecular mass is 288.38 g mol−1.

OK, what kind of reaction it will be - how will be the normality of substance related to molarity of the solution?
