If Avogadro number `N_(A)` is changed from `6.022xx10^(23) mol^(-1)` to 6`.022xx10^(20) mol^(-1)`, this would change:

Options

A. (a)the ratio of chemical species to each other in a balance equation
B. (b)the ratio of elements to each other in a compound
C. (c )the definition of mass in unit of gram
D. (d)the mass of one mole of grams

Answer

D

Explanation

`:'` mass of 1 mol `(6.022xx10^(23) "atoms")` of each `=12 g`
If Avogadro number `(N_(A))` is changes, then mass of `1 mol (6.022xx10^(20) "atom")` of carbon
`=(12xx6.022xx10^(20))/(6.022xx10^(23))=12xx10^(-3) g`
Therefore the mass of 1 mol of carbon is changed.
