Another Weight/Volume question



I think I should be using C=m/v

I divide the given volume by 10 but I'm not sure what to do with the Mr.

only 110.98 of 219.08 are actually the substance you need

Hence you have to weigh out 219.08/110.98 times as much as you would have done if you used the anhydrous compound

So 20*219.08/110.98?

I think it is not molar concentration, because they write w/v (weight/volume)
And we do not know what units we must use g/l or g/ml or kg/l and so on.
