Question

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 ratioof 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 1

Correct Answer - A
Mass of 1 mole `(6.022 xx 10^(23))` of carbon atoms = 12g
If `N_(A)` is changed to `6.022 xx 10^(200)`
then mass of 1 mole of carbon atoms
`= ((12g))/((6.022xx10^(23)))xx(6.022xx10^(20))=1.2xx10^(-2)g`.
