I am stumped on this homework problem. SOS please
A kitchen uses acetic acid (CH3OOH at 18M) to dilute it to produce vinegar at 5% m/v acetic acid concentration. What is the concentration in mil/L?

You have to show your attempts at solving the problem to receive help, this is a forum policy.

I am not sure I understand the question though (not necessarily your fault):

What is the concentration in mil/L?

Concentration of what?

And what is mil?

[Corribus]

Probably typo, mol/L. And I think the question is just asking to convert 5% m/v 18M acetic acid in water to mol/L, no?

[Heebeejibees]

Yes it should be mol/L and that is what it’s asking

[Borek]

OK, being before coffee didn't help, I thought you were asked to convert concentration to some strange unit, but it wasn't clear whether you are asked to convert 18 M or 5% m/v.

Yes it should be mol/L and that is what it’s asking

You have still not shown what you have tried.

5% m/v - what does it mean?

How much acetic acid in 1 L of 5% m/v solution?
