To make the calculation easy ie let the percentages convert directly to grams lets assume we have 100 g of vitamin C. Sulfur molten appears as a pale yellow crystalline solid with a faint odor of rotten eggsInsoluble in waterA fire and explosion risk above 450 F.

How to find the molecular formula of a compound given percentages. We want to find the number of moles of each element in order to determine the ratios of the elements and the formula. Handled at elevated temperature typically 290F to prevent solidification and makes transfers easier. If you are given mass percentages always work with a hypothetical 100-gram sample.

To determine the empirical formula from the mass percentages of the elements in a compound such as penicillin G we need to convert the mass percentages to relative numbers of atoms. Transported as a yellow to red liquid. From these mass percentages the empirical formula and eventually the molecular formula of the compound can be determined.
