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

  the   balanced   equation   for   reaction of   ca metal   with   o2 to   produce   cao   is as below

2 ca+ o2→ 2 cao2

  explanation

the reaction is   balanced     since the   number of atoms   in reactant side is   equal to   number of atoms   in   product side.   for   example   they   are 2   atom of   ca in   reactant   side   and   2   atoms of ca   in   the product side.

  the   process   is a   meet the   requirement   of   redox   reaction because :     calcium   is   oxidized   from   oxidation state 0   to 2+   while   oxygen   is reduced from   oxidation   state   0   to 2-
