Question

How many atoms of manganese do you have if you weigh out 54.94g of Mn?

Answer 1

Answer:

Number of atom = 6.022 x 10²³

Step-by-step explanation:

Given:

Mass of manganese = 54.94 gram

Find:

Number of atom

Computation:

Number of atom = [Mass of manganese / Atomic mass of manganese]Avogadro's number

Number of atom = [54.94 / 54.94]6.022 x 10²³

Number of atom = 6.022 x 10²³
