Is mol and m the same
WebThe definitions of amu and moles were intentionally chosen to make that happen (I'm surprised your teacher didn't explain this, actually). This allows us to easily relate masses at the atomic scale to masses at the macroscopic scale. To check this, look at the mass of an amu when converted to grams: 1 a m u = 1.6605 × 10 − 24 g WebThe resistance of 0.2 M solution of an electrolyte is 50 Ω. The specific conductance of the solution of 0.5 M solution of the same electrolyte is 1.4 S m-1 and resistance of the same solution of the same electrolyte is 280 Ω. The molar conductivity of 0.5 M solution of the electrolyte in Sm-2 mol-1 is. 5 x 10-4. 5 x 10-3. 5 x 10 3. 5 x 10 3
