Chemistry
Calculate the molarity and normality of the followingcompounds:
a.80 μg/L HNO^3
b.135 μg/L CaCO^3
c.10 μg/L Cr(OH)^3 – Chromium(III) hydroxide will dissociate inwater to form a chromium ion and 3 hydroxide ions. The charge of 1hydroxide ion is -1. The number (III) should also give you a hintto determine n.
