Question

If Avagadro Number $N_A$ is changed from $6.022\times {10}^{23}{mol}^{-1}$ to $6.022\times {10}^{20}{mol}^{-1}$ this would change

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

Answer 1

Answer: (C)

The mass of one mole of carbon

Avogadro number:

If Avogadro number $N_A$ is changed from $6.022\times {10}^{23}mo{l}^{-1}$ to $6.022\times {10}^{23}mo{l}^{-1}$. This would change the mass of one mole of carbon 12g $\to$ 12mg i.e 1 mol of carbon atom mass = 0.012gm.

Hence option $C$ is correct.
