How do i find molarity
WebMar 6, 2014 · Molarity is also known as the concentration. The concentration can be converted to pH. Take a sample of nitric acid HNO3 with a molarity of 0.0032 M. The molarity becomes the [H+] concentration of 3.2 × 10−3. We know this is the [H+] concentration because HNO3 is a strong acid, since the acid will completely dissociate …
