Answer:
The number of moles of O atom in mol of
= 1.6
Explanation:
1 molecule of contains 2 atoms of O
So, molecules of
contains
atoms of O.
We know that 1 mol of an atom/molecule/ion represents numbers of atoms/molecules/ions respectively.
So, molecules of
is equal to 1 mol of
.
atoms of O is equal to 2 moles of O atom.
Hence, 1 mol of contains 2 moles of O atom.
Therefore, mol of
contains
moles of O atom or 1.6 moles of O atom.
The correct answer is .
Organometallic chemistry is the study of organometallic compounds, which are substances that contain at least one chemical bond between a carbon atom from an organic molecule and a metal. These substances include alkali, alkaline earth, and transition metals, as well as metalloids like boron, silicon, and selenium. In addition to links to organyl fragments or molecules, bonds to 'inorganic' carbon, such as those to carbon monoxide (metal carbonyls), cyanide, or carbide, are also typically regarded as organometallic. Although they are not strictly speaking organometallic compounds, some similar compounds, such as transition metal hydrides and metal phosphine complexes, are frequently included in discussions of such substances. The phrase "metalorganic compound," which is comparable but different, describes molecules that contain metals but do not have direct metal-carbon bonds but do have organic ligands.

Answer: There are molecules in 63.00 g of
Explanation:
According to avogadro's law, 1 mole of every substance occupies 22.4 L at STP and contains avogadro's number of particles.
To calculate the moles, we use the equation:
1 mole of contains =
molecules
Thus 3.5 moles of contains =
molecules.
There are molecules in 63.00 g of
