Assertion :Both 12g of carbon and 27g of aluminium contain 6.023 × 1023 atoms. Reason :Molar mass of an element contains Avogadro number of atoms.
A.A✓ Correct
B.B
C.C
D.D
Explanation
We know that 1 mole = number of atoms present in 12 gram of 12C= 23 6.023 10 x Therefore, mass of 1 mole of substance= 23 6.023 10 x Similarly, 27 gram is the molar mass of aluminium. 67 MOLE & EQUIVALENT CONCEPT
