Al or aluminum is atomic number 13. A soft white ductile metal.
1 mole Al = 26.98g/mol (atomic weight in grams)1 mole Al = 6.022 X 1023 atoms AlConvert 2.78g Al to moles.2.78g Al x 1mol Al/26.98g = 0.103mol AlConvert moles Al to atoms Al.0.103mol Al x (6.022 x 1023atoms/mol) = 6.20 x 1022 atoms Al
By definition, 1 mole of anything is 6.022 x 1023 particles of that thing. So, 1 mole of Al = 6.022 x 1023 atoms Al 7.5mol Al x (6.022 x 1023 atoms Al/1mol Al)=4.5165 x 1024 atoms Al
To calculate the number of grams of Al in 371 g of Al2O3, you first need to determine the molar mass of Al2O3 (102 g/mol). Then, calculate the molar mass of Al (27 g/mol). From the chemical formula Al2O3, you can see that there are 2 moles of Al for every 1 mole of Al2O3. Therefore, by using these ratios, you can determine that there are 162 g of Al in 371 g of Al2O3.
The atomic number of any element depends on the number of protons it has in its nucleus. Aluminium has 13 protons hence making the atomic number of aluminum 13.
The atomic number of Al is 13.
Alcapone's number is 105
Al Montoya is number 35 on the Winnipeg Jets.
Al Horford is number 15 on the Atlanta Hawks.
Al Jefferson is number 25 on the Charlotte Hornets.
Al Alburquerque is number 62 on the Detroit Tigers.
Al Toon was number 87 while playing for the University of Wisconsin.
Al Kaline's jersey number was 6 throughout his career with the Detroit Tigers.
The oxidation number of Al in NaAlH4 is +3. This is because Na has an oxidation number of +1, H has an oxidation number of -1, and the overall compound has a neutral charge. Therefore, the oxidation number of Al can be calculated as +3.
32
