Aspirin has a molar mass of 180g/mol. if the empirical formula is c9h8o4, what is the molecular formula of aspirin ? fill in the blanks for the subscripts of the formula below. you have to have a whole number subscript for each blank even if it is a 1. c__h__o__

Explanation:

Molecular formula is the chemical formula which depicts the actual number of atoms of each element present in the compound.  Empirical formula is the simplest chemical formula which depicts the whole number of atoms of each element present in the compound.

The empirical formula is

The empirical weight of = 9(12)+8(1)+4(16)= 180g.

The molecular weight = 180 g/mole

Now we have to calculate the molecular formula:

The molecular formula will be=

Thus molecular formula of aspirin will be

answer is: c. the experiment shows that the red substance experienced a chemical change.

this is chemical change (chemical reaction), because two new substances are formed (metalig liquid and gas), the atoms are rearranged and the reaction is followed by an energy change.

this is example of chemical decomposition.

chemical decomposition (analysis) is the separation of a single chemical compound into its two or more elemental parts or to simpler compounds.  

chemical decomposition is opposite of chemical synthesis.

they it depends on if one believes about radioactivity, they make a geiger counter beep but maybe it was going to beep anyway electronics do wierd things all the time or it was programmed to beep near certain metals.
