Question

convert into mole 102.5g carbon​

Answer 1

Explanation:

Mole = Givan mass in gram/ moleculer mass

given mass =102.5 g

molecular mass of carbon = 12

$mole = \frac{102.5}{12} \\ \\ = 8.54$

Ans..

Answer 2

Mole = Mass/ Molecular mass

Mole = 102.5/Molar mass

Molar mass of carbon = 12

Mole = 102.5/12

Mole = 8.54

Thus the answer is 8.54
