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

Answer:

The number of sulfur atoms in 1 g of sulfur is:- $1.875\times 10^{22}$ atoms

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:-

$N_a=6\times 10^{23}$

Given atomic mass of sulfur = 32 u

Which means that:-

32 g of sulfur contains $6\times 10^{23}$ of atoms

Also,

1 g of sulfur contains $\frac {6\times 10^{23}}{32}$ of atoms

So, The number of sulfur atoms in 1 g of sulfur is:- $1.875\times 10^{22}$ atoms
