Why is the term molecular mass applied to water but the term formula mass applied to aluminum chloride?
The term molecular mass is used for water because it exists as discrete molecules containing two hydrogen atoms and one oxygen atom. Aluminum chloride, on the other hand, does not exist as discrete molecules but as an ionic compound made up of aluminum and chlorine atoms held together by ionic bonds. Therefore, the term formula mass is used to describe the total mass of one formula unit of aluminum chloride.
What is the molecular mass for AlBr3?
you take the mass of Al plus three Br. (27.0) + 3(80.0) the answer is 267.
What is the atomic mass of aluminum?
The atomic mass number of aluminum is 27. The atomic mass of aluminum is 26.98115386
What is the molecular mass of cytosine?
The molecular mass of cytosine is approximately 111.1 grams per mole.

Calculate the molecuar mass of alluminium sulphate?
The molecular formula of aluminum sulfate is Al2(SO4)3. To calculate the molecular mass, multiply the atomic mass of each element by the number of atoms present in the formula and then add them up. The molecular mass of aluminum sulfate is 342.15 g/mol.
How many moles of aluminum are present in 856g of aluminum sample?
To determine the number of moles of aluminum present in 856g, you need to divide the mass by the molar mass of aluminum. The molar mass of aluminum is approximately 26.98 g/mol. So, 856g ÷ 26.98 g/mol ≈ 31.7 moles of aluminum are present in 856g.

Mass of aluminum chloride?
The molar mass of aluminum chloride (AlCl3) is approximately 133.34 g/mol. To find the mass of aluminum chloride, you would need to know the amount of substance (in moles) and then use the molar mass to calculate the mass. For example, if you had 2 moles of aluminum chloride, the mass would be 2 moles * 133.34 g/mol = 266.68 grams.
What is the molecular mass for AlBr3?
you take the mass of Al plus three Br. (27.0) + 3(80.0) the answer is 267.
What is the atomic mass of aluminum?
The atomic mass number of aluminum is 27. The atomic mass of aluminum is 26.98115386
What is the molecular size of aluminum stearate?
The molecular size of aluminum stearate can vary depending on its structure and the number of aluminum and stearate units present in the molecule. It is a salt formed by the reaction of stearic acid and aluminum hydroxide, typically resulting in a larger molecular size compared to the individual components.
What is the mass of hexane?
I assume you mean the molecular mass. Its molecular mass is 86.175
What is the molecular for sucrose?
I assume you mean the molecular mass. Its molecular mass is 342.3g/mol
How many moles are in 4177 g of aluminum chloride?
Aluminum chloride has a formula of AlCl3, and its molecular weight is the sum of the atomic weights of its atoms. Al has a mass of 27.0, and Cl, 35.5. So we add the masses of Al (27.0) and the chlorides (3x34.5=106.5) to get a molecular weight of 133.5 grams per mole of AlCl3. If we have 4177g and divide it by 133.5g/mole, we get 31.30 moles.
What is molecular formula of aluminum?
al
What is the maximum mass of aluminum chloride that can be formed when reacting 13.0 of aluminum with 18.0 of chlorine?
I'm assuming you mean 13g of Aluminum and 18g of Chlorine Atomic mass of Al = 27g/mol number of moles = mass / atomic mass = 13g / 27g/mol = 0.481mol Molecular mass of Cl2 = 2(35.5) = 71g/mol number of moles = mass / atomic mass = 18g / 71g/mol = 0.254mol The balanced equation for reaction between Aluminum and Chlorine: 2Al + 3Cl2 --> 2AlCl3 The ratio of Al to Cl2 is 2:3 and there's only 0.254mol of Cl2 therefore it's completely reacted and Al is in excess. The ratio of Cl2 to AlCl3 is 3:2 and 0.254mol of Cl2 so there's (0.254mol x 2/3) = 0.169mol of AlCl3 formed. Molecular mass of AlCl3 : 27 + 3(35.5) = 133.5g/mol mass = number of moles x molecular mass = 0.169mol x 133.5g/mol = 22.56g of AlCl3
