Answer: C6H6
Explanation: Molecular Formula is the molecular mass divided by the empirical formula mass of CH which is C 12and H is 1 so 12 + 1= 13 g CH
Solution:
78.11 g CH / 13 g CH = 6

Answer:
Atomic Oribal
Explanation:
There are four basic types of electron orbitals – s, p, d, and f. (Visual representations can be found in the tutorial above.) The s subshell is a spherical orbital which can contain up to two electrons. Each energy level has one s subshell.
