Question

How many atoms are in 18.016g of Sulfur?

Answer 1

= 3.384 × 10^23 atoms

Step-by-step explanation:

We are given 18.016 g of sulfur

We are required to determine the number of atoms of sulfur

We will use the following steps;

Step 1: Determine the number of moles of sulfur

Number of moles = Mass ÷ molar mass

Molar mass of sulfur = 32.065 g/mol

Therefore;

Number of moles = 18.016 g÷ 32.065 g/mol

= 0.562 moles

Step 2: Determine the number of atoms

Using the Avogadro's constant;

1 mole of an element = 6.022 × 10^23 atoms

Therefore;

For 0.562 moles;

= 0.562 moles × 6.022 × 10^23 atoms

= 3.384 × 10^23 atoms

Therefore; there are 3.384 × 10^23 atoms in 18.016 g of Sulfur.
