Question

How many atoms are there in 8.80 moles magnesium chloride? (write your answer in scientific notation).

Answer 1

There are 5.30*10²⁴ atoms in 8.80 moles magnesium chloride.

Step-by-step explanation:

Avogadro's Number is called the number of particles that make up a substance (usually atoms or molecules) and that can be found in the amount of one mole of said substance. Its value is 6.023*10²³ particles per mole. Avogadro's number represents a quantity without an associated physical dimension. Avogadro's number applies to any substance.

Then you can apply the following rule of three: if 1 mole of magnesium chloride contains 6.023*10²³ atoms, 8.80 moles of magnesium chloride contain how many moles of atoms?

`amount of atoms=(8.80 moles* 6.023*10^(23) atoms )/(1 mole)`

amount of atoms= 5.30*10²⁴

There are 5.30*10²⁴ atoms in 8.80 moles magnesium chloride.
