Homework Statement:
how many grams of water to dilute 200ml noah (SG 1.32, 28.83%) to solution SG 1.157, 13.55%
Relevant Equations:
sg= density x / density h20
i am nonplussed about how to proceed with this dilution, probably it is very simple.

Hellp fox, :welcome: !

Work out your homework equation to turn this into a simple math problem and you'll be fine.
To do this, write a scenario, something like
200 ml NaOH of SG 1.32 weighs .. grams and consists of ... gram of H2O plus ... grams of NaOH
etc.
Then convert that into an expression in terms of symbols (not numbers) for the amount of water you need to add.

Here you are dealing with mass fractions, not molalities and certainly not molarities !
