Answer:
[tex]\boxed {\boxed {\sf About \ 138 \ grams \ of \ aluminum}}[/tex]
Explanation:
To convert from moles to grams, we must use molar mass.
This can be found on the Periodic Table, so look for the symbol for aluminum: Al
We can use this number as a ratio.
[tex]\frac { 26.981538 \ g \ Al} { 1 \ mol \ Al}[/tex]
Multiply by the given number of moles: 5.12
[tex]5.12 \ mol \ Al *\frac { 26.981538 \ g \ Al} { 1 \ mol \ Al}[/tex]
Multiply. The moles of aluminum will cancel.
[tex]5.12*\frac { 26.981538 \ g \ Al} { 1}[/tex]
[tex]138.145475 \ g \ Al[/tex]
Round. The original measurement of moles has 3 significant figures, so our answer must also have 3 sig figs.
For the number we calculated, that is the ones place. The 1 in the tenth place tells us to leave the 8.
[tex]138 \ g \ Al[/tex]
There is about 138 grams of aluminum in 5.12 moles.
