If Avogadro number N_A is changed from 6.022 10^ 23 mol^ -1 to 6.022 10^ 20 mol^ -1 , this would change:

JEE Main Chemistry question

If Avogadro number is changed from mol to mol, this would change:

(A)The mass of one mole of carbonCorrect
(B)The ratio of chemical species to each other in a balanced equation
(C)The ratio of elements to each other in a compound
(D)The definition of mass in units of grams

Answer: (A)

Solution

Redefining Avogadro's number changes how many actual atoms correspond to "1 mole", and hence changes the physical mass that 1 mole of carbon (or any substance) represents.
