Answer:
There are 9.0345*10²³ in 1.5 moles of Hg.
Step-by-step explanation:
The Avogadro Number or Avogadro Constant is called the number of particles that constitute a substance (usually atoms or molecules) and that can be found in the amount of one mole of that substance. Its value is 6.023 * 10²³ particles per mole. Avogadro's number applies to any substance.
Then a rule of three can be applied to calculate the number of atoms in 1.5 moles of Hg. This rule applies as follows: if 1 mole of Hg contains 6,023 * 10²³ atoms, 1.5 moles how many atoms of the element will they contain?
![Number of atoms=(1.5 moles* 6.023*10^(23)atoms )/(1 mole)](https://img.qammunity.org/2020/formulas/chemistry/middle-school/cltw9xmnkdoy2bf4j9svt987atjd6lf50y.png)
Number of atoms=9.0345*10²³
There are 9.0345*10²³ in 1.5 moles of Hg.
