Question

Sulfur has an atomic mass of 32 u and Avogadro's number is 6 × 1023 formula units/mole. The number of sulfur atoms in 1 g of sulfur is:___________

Answer 1

The number of sulfur atoms in 1 g of sulfur is:-
`1.875* 10^(22)` atoms

Step-by-step explanation:

Avogadro’s number represent the number of the constituent particles which are present in one mole of the substance. It is named after scientist Amedeo Avogadro and is denoted by
`N_0`.

Avogadro constant:-

`N_a=6* 10^(23)`

Given atomic mass of sulfur = 32 u

Which means that:-

32 g of sulfur contains
`6* 10^(23)` of atoms

Also,

1 g of sulfur contains
`\frac {6* 10^(23)}{32}` of atoms

So, The number of sulfur atoms in 1 g of sulfur is:-
`1.875* 10^(22)` atoms
