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 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

Answer

B

Explanation

If Avogadro number `N_(A)` , is changed from `6.022xx10^(23)"mol"^(-1)to6.022xx10^(20)"mol"^(-1)`, this would change the mass of one mole of carbon.
`:'` 1 mole of carbon has mass -12 g
or `6.022xx10^(23)` atoms of carbon have mass =12 g
`:.6.022xx10^(20)` atmos of carbon have mass
`=(12)/(6.022xx10^(23))xx6.022xx10^(20)=0.012g`
