Question

12 grams of carbon has 'n' number of atoms . then what will be the no. of atoms present in 12 grams of magnesium ?​

Answer 1

$\sf\fbox\red{Answer:-}$

$chlorine \: ion , \: c {l}^{ - }$

Answer 2

Answer:

n/2

Explanation:

If 12g of carbon contains n atoms it means that atomic mass = n atoms. So mass of magnesium =24 so in 24g there will be n atoms so in 12g it will be n/2

Lets do step by step 1 mole of carbon = gram molecular mass of carbon = 12 grams. 1g carbon = 1/12 mole 1g of carbon contains x atoms and 1g = 1/12 mole. Therefore 1/12 mole of carbon has x atoms so 1/12 mole of magnesium also contains x atoms. 1 mole of magnesium = 24g Therefore, 24 gram = 1 mole 1g = 1/24mole. 1/12 mole of magnesium = x atoms 1/24 mole of magnesium = x x 12/24 ( x multiplied by 12, divide by 24) = x/2 atoms 1 gram of magnesium has x/2.
