what is the molecular formula if the emperical formula C2H5 and the molcuar molar mass is 58.14 g/mol0​

C4H10

Explanation:

Remark

Every periodic table is different. I'm going to use approximate numbers.

Emperical Formula Mass

2C   =   2 * 12 =  24

H5   =   5     1       5

Emperical Formula Mass = 29

Solution

To get the molecular Molar Mass, you use

Molecular Molar Mass = number of mol of each constituent * empirical molar mass

Molecular mass = 58.14 rounded to 58

empirical mass =  29

moles = constitutent = ?

58 = 29 * mols constituent     Divide by 29

2 = moles constituent

Answer

(C2H5)_2

C4H10
