Question

Convert 13.5 g C2H60 to atoms of Carbon​

Answer 1

Answer:

3.49×10²³ atoms of C

Explanation:

Given data:

Mass of C₂H₆O = 13.5 g

Number of atoms of carbon = ?

Solution:

First of all we will calculate the number of moles of C₂H₆O

Number of moles = mass/molar mass

Number of moles = 13.5 g/46.07 g/mol

Number of moles = 0.29 mol

1 mole of C₂H₆O  contain = 2 mol of C

0.29 mol× 2 = 0.58 mol

Now we will calculate the number C atoms.

1 mole = 6.022×10²³ atoms

0.58 mol×6.022×10²³ atoms  / 1 mol

3.49×10²³ atoms of C
