To find the number of sulfur atoms in a given mass of sulfur, you can use the following steps:

Determine the number of moles of sulfur using the formula:

moles

=

mass

molar mass

moles=

mass

Given that the molar mass of sulfur (

S

S) is 32.06 g/mol and the mass (

m

m) is 1.56 g:

Once you have the moles of sulfur, you can use Avogadro's number (6.022 x
