Question

find the number of atoms in 0.5 moles of calcium atom​

Answer 1

Answer:

Explanation:

Number of atoms can be found by simply multiplying no of moles with avagadro number.

So,no of calcium atoms= 0.5 * 6.02*10^23

= 3.01*10^23 atoms

Hope it will help you

Answer 2

Number of atoms is 3*10²³.

Given - Number of moles

Find - Number of atoms

Solution - The number of atoms in 1 mole of any substance is equal to Avogadro's number. Avogadro's number= 6.022*10²³.

Number of atoms in 0.5 moles = 6.022*10²³*0.5

Performing multiplication

Number of atoms = 3*10²³

Hence, 0.5 moles of calcium has 3*10²³ number of atoms.
