If Avogadro number N(A) is changed from ...

If Avogadro number `N_(A)` is changed from `6.022 xx 10^(23) mol^(-1)` to `6.022 xx 10^(20) mol^(-1)`, this would change

A

The definition of mass in units of grams

B

The mass of one mole of carbon

C

The ratio of chemical species to each other in a balanced equation

D

The ratio of elements to each other in a compound

Text Solution

Verified by Experts

The correct Answer is:
B
`because ` mass of 1 mol (`6.022 xx 10^(23)` atoms) of carbon = 12 g
If Avogadro number `(N_(A))` is changed then mass of 1 mole (`6.022 xx 10^(20)` atom) of carbon
` =(12 xx 6.022 xx 10^(23))/(6.022 xx 10^(23))= 12 xx 10^(3)g`
Therefore, the mass of 1 mol of carbon is changed.
