Question

what information does a molecular formula give?
a. the order in which atoms are bonded in a molecule
b. the lowest ratio of atoms in a molecule
c. the actual number of atoms in a molecule
d. the percent composition of atoms in a molecule

Explanation:

A molecular formula shows the actual number of each type of atom present in a single molecule of a compound. It does not show the order of atom - bonding (that's structural formula), the lowest ratio of atoms (that's empirical formula), or percent composition (which requires additional calculations based on molar masses).

Answer:

C. The actual number of atoms in a molecule
