If Avogadro number NA is changed from 6....

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 mass of one mole of carbon

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.

Text Solution

Verified by Experts

The correct Answer is:
A
Mass of 1 mol `(6.022 xx 10^(23) `atoms) of carbon = 12 g If Avogadro number is changed to `6.022 xx 10^(20)` atoms then mass of 1 mol of carbon
` = ( 12 xx 6.022 xx 10^(20))/( 6.022 xx 10^(23)) = 12 xx 10^(-3) g`
