Chemistry - Combined Moles

Scroll to see replies

This question is not possible without knowing the volume of the solution formed.

The definition of concentration (molarity) is moles of solute per litre of SOLUTION.

Unless you are in the USA and working in Molality.

So you can't work it out?

Not just me, anyone, given the information available.

I suspect that it's just a lazily written question.

Yeah, I was referring to everyone when I said 'you'. sorry

so lads i was tryna do this question and find it online but i worked it out with a really simple formula for to find the amount of moles from the volume of gas which is: moles = volume / molar gas volume (this is always 24dm^3) and so the moles of gas would be 392/24=16.333333... then you divide by the volume of the solvent which is 2.65dm^3 and the final concentration of the resulting solution would be 6.16mol/dm^3.

I am a bit late to this thread lol but if anyone else is tryna find how to do these types of questions here you are, just remember the formula - moles = volume(dm^3) / molar gas volume (always 24dm^3).
