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 grams
Correct Answer: D
Solution :
\[\because \]mass of mol (\[6.022\times {{10}^{23\,}}\]atoms) of each = 12 g If Avogadro number \[({{N}_{A}})\]is changed, then mass of 1 mol (\[6.022\times {{10}^{20}}\]atom)of carbon \[=\frac{12\times 6.022\times {{10}^{20}}}{6.022\times {{10}^{23}}}=12\times {{10}^{-3}}g\] Therefore the mass of 1 mol of carbon is changed.You need to login to perform this action.
