* Molar Mass Calculation: Molar mass is calculated by dividing the mass of the substance by the number of moles.
* Insufficient Liquid: Using less liquid means you have a smaller mass. Since the number of moles remains the same (assuming the concentration is constant), a smaller mass leads to a larger calculated molar mass.
Example:
Imagine you need to measure the molar mass of a liquid. You're supposed to use 10 grams of the liquid, but you accidentally use only 5 grams.
* Correct calculation: (10 g / moles) = molar mass
* Incorrect calculation: (5 g / moles) = molar mass (which will be double the correct value)
In summary: Using too little liquid leads to an underestimation of the mass, resulting in an overestimation of the molar mass.
