Yes, seawater contains water H2O and NaCl as an absolute minimum. It also contains traces of many other molecules and species.
Every single organic molecule contains two or more atoms.
Pyrite's chemical formula is FeS2, meaning that it contains 1 atom of iron for every 2 atoms of sulfur. There is no oxygen in pyrite.
A gram atomic mass of helium (He) contains the same number of atoms as 1 mole of helium. Since 1 mole of any substance contains approximately 6.022 x 10^23 atoms, a sample of helium with a gram atomic mass would contain that same number of atoms.
C9H804 contains a total of 12 atoms.
Yes, seawater contains water H2O and NaCl as an absolute minimum. It also contains traces of many other molecules and species.
Every single organic molecule contains two or more atoms.
One mole of neon contains Avogadro's Number of atoms (approximately 6.02 x 1023).
Yes. Every glucose molecule contains twelve hydrogen atoms.
Every organic substance contains carbon atoms.
Yes. Molecules are the combination of atoms. Therefor every substance contains molecules.
Petrol (gasoline) usually has an octane rating. It is a mixture. Since Octane is C8 a molecule of petrol (gasoline) contains approximately 8 carbon atoms.
It is found everwhere, as in each and every biomolecule contains at least some hydrogen atoms.
A gram atomic mass of helium (He) contains the same number of atoms as 1 mole of helium. Since 1 mole of any substance contains approximately 6.022 x 10^23 atoms, a sample of helium with a gram atomic mass would contain that same number of atoms.
Pyrite's chemical formula is FeS2, meaning that it contains 1 atom of iron for every 2 atoms of sulfur. There is no oxygen in pyrite.
That would be FALSE. One mole of every atom contains the same number of atoms, and that number is 6.02x10^23 atoms.
C9H804 contains a total of 12 atoms.
