A compound has a molecular weight of 146 g/mol. A 0.3250 g sample of the compound contains 0.1605 g of carbon, 0.0220 g of hydrogen, and 0.1425 g of sulfur. What is the molecular formula of the compound

The molecular formula is

Explanation:

We are given:

Mass of = 0.1605 g

Mass of = 0.0220 g

mass of = 0.1425 g

Step 1 : convert given masses into moles.

Moles of C =

Moles of H =

Moles of S =

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

For C =

For H =

For S =

The ratio of C : H: S=  3: 5: 1

Hence the empirical formula is

The empirical weight of = 3(12)+5(1)+1(32)= 73g.

The molecular weight = 146 g/mole

Now we have to calculate the molecular formula.

The molecular formula will be=
