1 mole of
is 180 grams. (Molar mass).
18 is
of 180 , so it means 18 grams of
is
moles
To find a molecule's molar mass, you should multiply each atom's number with their atomic mass, in the molecule and add them I mean, there are 6 Carbon atoms, 12 Hydrogen atoms and 6 Oxygen atoms. So,
Atomic mass of Carbon is approximately, 12 amu (atomic mass unit), Hydrogen's is approximately, 1 and Oxygen's is approximately, 16. So :
When a molecule loses or gains an electron it becomes an ion.
"If it gains a negative electron, it becomes a negative ion. If it loses an electron it becomes a positive ion."
