Answer 1

Number of moles = 0.153 mol

Step-by-step explanation:

Given data:

Mass of sulfur = 5 g

Number of moles of sulfur atom = ?

Solution:

Formula:

Number of moles = mass/molar mass

Molar mass of sulfur is 32. 065g/mol.

By putting values,

Number of moles = 5 g/ 32.06 g/mol

Number of moles = 0.153 mol
