PROPERTIES:H2CO3
58 protons
82 neutrons
Atomic Mass= 140 Atomic Number= 58
USES:Pop (coke, pepsi, etc.), champagne, and other bubbly drinks.
Answer 2: The answer above is not correct. Molecules have atomic mass, but do not have atomic number, otherwise they look like elements.
Furthermore, atomic mass of H is 1 (2x), C is 12, O is 16 (3x), giving a total of 62. The accurate atomic mass is: 62.02529 g per mole.
I repeat: carbonic acid does not have an atomic number, even though it contains 32 protons.
