<u>Given that:</u>
1.30 x 10²¹ molecules of aspirin C₉H₈O₄
<u>Question:</u>
The mass, in grams
<u>The Process:</u>
Firstly, we prepare the molar mass of aspirin C₉H₈O₄.
Relative atomic mass (in rounding to integers):
- C = 12 g/moles
- H = 1 g/moles
- O = 16 g/moles
In aspirin, there are 9 carbon atoms, 8 hydrogen atoms, and 4 oxygen atoms. Therefore the molar mass is given by
Secondly, we calculate the moles of 1.30 x 10²¹ molecules of aspirin.
Remember this, one mole contains 6.02 x 10²³ molecules, which is called The Avogadro's number.
Let's convert 1.30 x 10²¹ molecules to the number of moles.
We get
Finally, we calculate the mass in grams.
Thus the mass of 1.30 x 10²¹ molecules of aspirin C₉H₈O₄ is 0.39 grams.
