If Avogadro number NA, is changed from 6.022 × 1023 mol-1 to 6.022 × 1020 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.

Answer - (a) the mass of one mole of carbon

Solution - avagadro no = 6.023 x 1023 , i,e the no. of carbon atoms in 1 mole of C

i,e 1 mole =  6.023 x 1023  atoms = 12g of C

thus, 6.023 x 1020  atoms =$12\times{6.023\times10^{20}\over6.023\times10^{23}}$

= 0.012g
