How many moles are present in 100. g of aspirin (c2h804, molar mass 180.2 g/mol)? 0.555 mol of aspirin 1.80 mol of aspirin 18.0 mol of aspirin 100. mol of aspirin

0.555 mol of aspirin

Explanation:

Given,

Mass of aspirin = 100 g

Molar mass of aspirin = 180.2 g/mol

To find, moles of aspirin in 100 g of mass = ?

The formula for the calculation of moles is shown below:

Thus,

Moles of aspirin in 100 g = 0.555 moles

c. heat could easily travel through the molecules in the air and escape/enter the flask. removing the air slows down the heat transfer.  

the answer to this question is 3.
