### When was stoichiometry discovered?

You can't really say that stoichiometry was "discovered" because stoichiometry is a mathematical process. It requires you to convert various quantities using a technique called dimensional analysis. The quantities involved, such as the mole, were discovered independent of each other, sometimes hundreds of years apart. If pressed for a date, I'd go with the discovery of the mole, which was first proposed in 1811 but not calculated until 1865.

### What is difference between liters and g-mole?

The mole is a counting unit, in scientific notation this is the mole: 6.2x10Â²Â³ (23) it's mostly used to measure mass of atom and molecules...and gas number of gram in 1 mole is equal to the numerical value of atomic mass first convert litres in gram and find out the number of gram in 1mol....it's goin to be the atomic mass of the liquid. the difference is certainly in the produce states, litres is a…

### How do you express mole fraction in mole percent?

Mole fraction and mole percent are essentially describing the same quantity, only mole percent uses the conversion of a number to a percentage. That's all the difference there is. Hence, a mole fraction of 0.134 for a component in a mixture is equivalent to 13.4 % in mole percent of that component. Mole percent spans the range from 0 to 100% while mole fraction spans the real values from 0 to 1.
