Explanation:
Standard formation of an substance is defined as formation of one mole of substance from its constituting elements.
Chromium(III) nitrate is composed of chromium, nitrogen and three oxygen atoms.
A balanced chemical equation for the standard formation reaction of solid chromium(III) nitrate
3.50 grams carbon 12 (1 mole C(12)/12.0 grams)(6.022 X 10^23/1 mole C(12))
<span>= 1.76 X 10^23 atoms</span>
Condensation.
If you think about the condensation you may find on your windows on a frosty morning, this may help you to remember :]
