Answer: 7.56 moles

Explanation:

C3H8 is the chemical formula for propane, the third member of the alkane family.

Recall that based on Avogadro's number, 1 mole of any substance has 6.02 x 10^23 atoms

So 1 mole of C3H8 = 6.02 x 10^23 atoms

Z moles of C3H8 = 4.55 x 10^24 atoms

To get the value of Z, we cross multiply:

1 x 4.55 x 10^24 atoms = Z moles x (6.02 x 10^23 atoms)

4.55 x 10^24 atoms = Z moles x (6.02 x 10^23 atoms)

To get the value of Z divide both sides by 6.02 x 10^23 atoms

Z moles =4.55 x 10^24 atoms ➗ 6.02 x 10*23 atoms

Hence, Z = 7.56 moles

Thus, the number of propane, C3H8 is 7.56 moles

How fast will benzene solidify
White raven [17]

Explanation:

What benzene is

Benzene is a chemical that is a colorless or light yellow liquid at room temperature. It has a sweet odor and is highly flammable.

Benzene evaporates into the air very quickly. Its vapor is heavier than air and may sink into low-lying areas.

Benzene dissolves only slightly in water and will float on top of water.

Why should the mole to mole ratio be a whole number ratio?​
muminat

Answer: The mole to mole ratio are the stoichiometric factors of the chemicals in your balanced reactions and are always in whole numbers. When we balance a chemical reaction, whole numbers are always used for easy convention.
