Compound has a molar mass of and the following composition: elementmass % carbon47.09% hydrogen6.59% chlorine46.33% Write the molecular formula of .

The given question is incomplete. The complete question is:

Compound X has a molar mass of 153.05 g/mol and the following composition:

elementmass %

carbon47.09%

hydrogen6.59%

chlorine46.33%

Write the molecular formula of X.

The molecular formula of X is

Explanation:

If percentage are given then we are taking total mass is 100 grams.

So, the mass of each element is equal to the percentage given.

Mass of C= 47.09 g

Mass of H = 6.59 g

Mass of Cl = 46.33 g

Step 1 : convert given masses into moles.

Moles of C =

Moles of H =

Moles of Cl =

Step 2 : For the mole ratio, divide each value of moles by the smallest number of moles calculated.

For C =

For H =

For Cl =

The ratio of C : H: Cl= 3: 5 :1

Hence the empirical formula is

The empirical weight of = 3(12)+5(1)+1(35.5)= 76.5g.

The molecular weight = 153.05 g/mole

Now we have to calculate the molecular formula.

The molecular formula will be=
