= 176 g/mole
= 176g
176 g/mol, or 176.12412 g/mol using accurate atomic weights. (We'll round off the molarity later.)
Find the mole of Ascorbic first:
= 1g * (1 mole / 176g)
Don't forget, you used 0.05 g, not 1 g.
The molarity should be given to three significant figures at least, four would be better (more common for accurate work like this). The given information is a little vague about significant figures, unfortunately!
