How many carbon atoms are present in 0.52 moles of C2H6O?

6.26 * 10²³ Carbon Atoms

Solution:

First calculate the number of C₂H₆O molecules present in 0.52 moles using following formula,

# of Molecules = Moles * 6.022 * 10²³

# of Molecules = 0.52 * 6.022 * 10²³

# of Molecules = 3.13 * 10²¹ Molecules

Secondly Calculate the Number of carbon atoms,

As,

1 Molecule of C₂H₆O contains = 2 Carbon Atoms

So,

3.13 * 10²¹ Molecules of C₂H₆O will contain = X Carbon Atoms

Splving for X,

X = (3.13 * 10²¹ Molecules * 2 Carbon Atoms) : 1 Molecule

X = 6.26 * 10²³ Carbon Atoms
