How many grams of Al2O3 are formed from 3 moles of O2?
If the reaction is just between O2 and Al, the balanced equation would be:3O2 + 4Al -> 2Al2O3By using the coefficients of the equation, we see that from 3 moles of O2 we get 2 moles of Al2O3. To find out how much this is in grams, we need to find the molar mass of Al2O3 . This is just the sum of the atomic masses of each atom that makes it up. (Use a periodic table to find atomic masses) So we get:26.98*2+16*3= 102.0One mole equals 102g, so the 2 moles produced by the reaction would amount to 204g.
How much energy is required to raise the temperature of 3 kg aluminum from 18 degrees Celsius to 23 degrees Celsius?
Specific heat af aluminum is 0.89 J/gC, so I will convert to grams for my convince.3 kg Al (1000 g/1 kg) = 3000 grams Alq = mass * specific heat * change in temperatureq = (3000 grams)(0.89 J/gC)(23 C - 18 C)= 1 X 104 Joules==============( as per significant figures )

What does 1 cu ft of aluminum weigh?
The weight of 1 cu. ft. of aluminum is approximately 169 pounds. It is also equivalent to 76,500 grams or 76.5 kilograms. The chemical symbol for aluminum is Al.
What is the contribution of al-haitham in the field of physics?
Abu Ali al-Hasan ibn al-Hasan ibn al-Haytham (965 in Basra - c. 1040 in Cairo) was a prominent scientist and polymath from the 'Golden Age' of Muslim civilization. He is commonly referred to as Ibn al-Haytham, and sometimes as al-Basri, after his birthplace in the city of Basra. He is also known by his Latinized name of Alhzen or Alhacen. Ibn al-Haytham made significant contributions to the principles of optics, as well as to physics, astronomy, mathematics, ophthalmology, philosophy, visual perception, and to the scientific method. He was also nicknamed Ptolemaeus Secundus ("Ptolemy the Second") or simply "The Physicist" in medieval Europe. Ibn al-Haytham wrote insightful commentaries on works by Aristotle, Ptolemy, and the Greek mathematician Euclid.
What is the mass in grams for 4.5 moles of aluminum?
2.38 mol Al
What is 3.56 mol Al in grams?
3,56 mol Al is equal to 96,05 grams.
What is the mass of 3 mol of Al?
As the periodic table of Elements states, Al has a Molar Mass (Grams/Mole) of 27.0g/mol. So 3 mols of Al mass is the same as 3 times 27.0g/mol. So, the equation is as follows: 3mols x 27.0g/mol = 81.0g. The reason on why it ends with grams is because the unit of moles in 3 will cancel out with the unit of mols in 27.0g.
What is the mass of four moles of aluminium?
For this you need the atomic mass of Al. Take the number of moles and multiply it by the atomic mass. Divide by one mole for units to cancel.2.00 moles Al × (27.0 grams) = 54.0 grams Al
How do you convert 5 grams of Al to mole?
To convert grams of aluminum to moles, you need to divide the given mass (5 g) by the molar mass of aluminum (26.98 g/mol). Therefore, 5 g of aluminum is equal to 5/26.98 = 0.185 moles of aluminum.
What percentage composition of Al2O3 is aluminum?
Molar Mass of Al: 2(27.0g/mol) = 54.0g/mol Molar Mass of O: 3(16.0g/mol) = 48.0g/mol Molar Mass of compound: 102.0g.mol (54.0g/mol / 102.0g/mol) x 100% = 52.9%
What is the mass of 4.35 moles of aluminum?
One mole weights 26.98 grams, so it is arouind 27 g. So 4 moles weight almost 108 grams.
How many moles are there in 150 grams of Al(OH)3?
To determine the number of moles in 150 grams of Al(OH)3, we first need to calculate the molar mass of Al(OH)3: Aluminum (Al) has a molar mass of 26.98 g/mol, oxygen (O) has a molar mass of 16.00 g/mol, and hydrogen (H) has a molar mass of 1.01 g/mol. Molar mass of Al(OH)3 = 26.98 + 3(16.00) + 3(1.01) = 78.03 g/mol Now, we can calculate the number of moles: Number of moles = Mass (g) / Molar mass Number of moles = 150 g / 78.03 g/mol ≈ 1.92 moles.
How many moles aluminum exist in 100.0 grams of aluminum?
The formular you need is M = n/m (molar mass = amount of substance/mass), or n = m/MAluminium has a molar mass of 26.982 g/mol. The given mass is 3 grams. Therefore:n(Al) = 3g / (26.982g/mol) = 0.11mol
What is the number of moles in 54 grams of aluminum?
For this you need the atomic mass of Al. Take the number of grams and divide it by the atomic mass. Multiply by one mole for units to cancel.54.0 grams Al / (27.0 grams) = 2.00 moles Al
2.91 moles of aluminum are how many grams?
For this you need the atomic mass of Al. Take the number of moles and multiply it by the atomic mass. Divide by one mole for units to cancel.2.91 moles Al × (27.0 grams) = 78.6 grams Al
Convert 62.13 kg of Al to moles?
Convert 62.13 kg Al to grams.62.13 kg (1000 g/kg) = 62130 g AlConvert grams to moles using the atomic weight of Al from the periodic table.Al is 26.9815 g/mol62130 g / (26.9815 g/mol) = 2302.6 mol AlIn significant figures, that is 2303 mol Al.In scientific notation, that is 2.303 x 104 mol Al.
