Question

How many moles of hydrogen atoms are in 92g of ethanol ?

Answer 1

if one mole of alcohol contain hydrogen atoms in one more there are six hydrogen atoms if there are 92 gram alcohol then it will produce 6 moles

Answer 2

The mass of ethanol (C₂H₅OH) = 92 g.

To find the number of moles of Hydrogen present in 92 grams of ethanol.

Calculation,

1 mole of ethanol (C₂H₅OH) contains 6 moles of hydrogen.

Now, we calculate the number of moles of 92 grams of ethanol.

We know that the Gram Molecular Weight of ethanol (C₂H₅OH) is:

(2 × 12) + (5 × 1) + (1 × 16) + (1 × 1)

= 46 g.

(As Atomic mass of carbon, hydrogen, and oxygen are 12, 1, and 16 respectively).

⇒ $n=\frac{92}{46}$

⇒ n = 2 moles.

If 1 mole of C₂H₅OH contains 6 moles of Hydrogen atom then 2 moles of C₂H₅OH contain 12 moles of hydrogen atom.

Therefore, the number of moles of H atom in 92 g of ethanol is 12.
