Okay so I am doing an experiment where I need to find the volume and flow rate needed to add .5% HF to 100g of material. The material is LMO (lithium manganese oxide).

How would I find the volume of 1% HF gas needed to have .5% HF in 100g LMO?
Would I first use 22.4L per mole, find the moles of HF through .5g F (.5% =.5g of F)
Then change moles of F to L?

And for the rate: I need to find the rate necessary for one hour of flow time.

Thanks for any help.

I guess the way I stated my question is a bit confusing....

Would I be able to apply this to help me solve for the volume of gas I'm looking for?
