Calculate the molecular formulas of the compounds having the following empirical formulas and molar masses: C₂H₅, 58 g/mol; CH, 78 g/mol; and HgCl, 236.1 g/mol.

the atomic number will stay the same no matter how many electrons it has, so it doesn’t decrease nor increase. it’ll only change with a different number of protons

the answer is:  

line graphs show patterns in data with variables that change over time; whereas, circle graphs show data as parts out of a whole (such as out of 100%).
