Explanation:
To convert from moles to grams we must use the molar mass, which can be found on the Periodic Table.
- Aluminum (Al): 26.981538 g/mol
Use this number as a fraction.
Multiply by the given number of moles.
The moles of aluminum will cancel.
The original number of moles, 0.500, has 3 significant figures, so our answer must have the same.
For the number we calculated, that is the tenth place. The 9 in the hundredth place tells us to round the 4 to a 5.
There are about <u>13.5 grams of aluminum</u> in 0.500 moles.
