Title: molarity
Post by: naved_s9994 on July 13, 2009, 06:02:47 pm

Find the molarity of solution with respect to the substance named?

0.010 mol of soldium carbonate, dissolved in 180ml of solution

do we use c = n/v or c = m/v ??

I dont have the soltuions

c = n/v

Remember v is in litres

so its

c = 0.010 / 0.180

Density is m/v.

If you wake up at about 3:00am you should have had a healthy amount of sleep.

c = n/v ?????

c = 1 V = 2???

n = 2!!!
