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

Options

A. the ratio of chemical species to each other in a balanced equation.
B. the ratio of elements to each other in a compound.
C. the definition of mass in units of grams
D. the mass of one mole of carbon.

Answer

D

Explanation

Mass of 1 mol `(6.022 xx 10^(3))` atoms of carbon = 12(g)
if Avogadro number is changed to `6.022 xx 10^(20)`atoms, then mass of 1 mol of carbons
`=(12.6 xx 6.022 xx 10^(20))/(6.022 xx 10^(23))`
`=12 xx 10^(-3)`g
