Question

One mole of every Substance has same mass

• A. True
• B. False

Answer 1

The correct option is B False

According to the Mole concept,

$\mathrm{Number}\mathrm{of}\mathrm{mole}=\frac{\mathrm{mass}\mathrm{of}\mathrm{element}\mathrm{in}\mathrm{grams}}{\mathrm{Gram}\mathrm{atomic}\mathrm{mass}}$

Hence, For one mole of Substance Mass of Element = Gram atomic mass of that Element

Since, Every substance has different gram atomic mass,

Hence, One mole of every Substance has same mass this statement is False
