Question

1. 24 gm Mg contains
atoms of magnesium.
1.6.23 x 10-23
2. 6.623 x 10-24
3. 6.023 x 1023
4.6.23 x 1023​

Answer 1

Answer:

$\huge \mathtt{ANSWER}$

Explanation:

• moles of C = 1212 =1
• moles of Ca = 4020 =0.5
• moles of O = 1632 =2
• moles of K = 3940 =1.025

As 1 mole of every element contains Avogadro number of atoms. Hence, Equal number of moles of different elements will contain same number of atoms. Therefore, 12 g of Magnesium will have same number of atoms as in 20 g of Calcium.
