Question

If a 0.489 M solution of L-ascorbic acid is being prepared what mass of solid (in grams) must be added to make a 500 ml of solution?

Answer 1

Approx...`40*g...`

Explanation:

By definition `"concentration"-="moles of solute"/"volume of solution"`

And so....`0.489*mol*L^-1-="moles of solute"/(0.500*L)`

`"moles of solute"=0.2445*mol`

`"mass of solute"=0.2445*molxx176.12*g*mol^-1=??*g`
