Sample (3.585g) contains 1.388g of C, 0.345g of H, 1.850g of O and its molar mass is 62g. What is the molecular formula of this

Attached is the solution:

Initially, convert the mass into moles.

Then, divide each mole by the smallest amount to identify the number of atoms in the empirical formula.

Next, calculate the empirical formula mass.

Then, determine the molecular formula by dividing the molar mass by the empirical formula mass.

Finally, multiply the empirical formula by the obtained answer to arrive at the molecular formula of the compound.
