What is the formula mass of ethyl alcohol, #C_2H_5OH#?

Answer 1

46.08 gram per mole (g/mol)

We must determine the atomic weights of the constituent elements—in this case, carbon, hydrogen, and oxygen—in order to arrive at this conclusion.

The following elements' atomic weights, expressed to the nearest hundredth:

12.01 g/mol for carbon, 16.00 g/mol for oxygen, and 1.01 g/mol for hydrogen

Let's now calculate the total number of each element bonded in the compound, expressed in moles:

Two carbons, one oxygen, and six hydrogens

We must multiply each element's atomic weight by the corresponding number of moles in the compound in order to find the formula.

Hydrogen: 1.01 x 6 = 6.06; Carbon: 12.01 x 2 = 24.02; Oxygen: 16.00 x 1 = 16.00

The total comes to 48.08 grams per mole, which is also known as the atomic mass unit.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
