Told by whom? Are you meant to be preparing some sort of solution to drink? Per litre of what - water?

As hinted above - what you have been told is meaningless. μmol/L is a concentration, so you've not been told how much of this solution to take, so you can't convert it into mg.

The molecular mass of vit C is 176.12 g/mol. A μmol is 1 millionth of a mol. So 1000μmol is 1/1000th of a mol which would be 0.17612g or 176.12mg

But - to get what you've been told, you would then have to dissolve this in a litre of water!

So the question then is - how many litres of this water are you then supposed to drink?

The recommended intake for vit C is 75mg per day. More if pregnant

So at a dilution of 1000μmol/L, to get the recommended daily intake of vit C you would need to drink just over 500ml of this solution.

Vit C tablets are typically 1000mg. So to get the same as this, you'd need to drink nearly 6 litres of a 1000μmol/l solution, or 3 big pop bottles full.

Wouldn't it be easier just to take a 1000mg tablet?

Apologies for the funny hour of the post - nightime roadworks a couple of streets away are keeping me awake!!!
