Question

One mole of Ca is equal to how many atoms​

Answer 1

Answer:

1 mole of calcium contains 6.023 $\times$ $10^{23}$ atoms.

Explanation:

1 mole is the amount of a substance that contains exactly $6.023\times 10^{23}$ constituent particles. 1 mole of a substance is always equal to the atomic mass of the element.

Hence, 1 mole of calcium will also have $6.023\times 10^{23}$ atoms.

Number of atoms in 1 mole calcium = 6.023 $\times$ $10^{23}$ atom
