Calculating the number of particles

  1. The number of particles in a substance can be calculated using:
  2. Number of particles = Avogadro constant × the amount of substance in mol.
  3. Calculate the number of water molecules in 0.5 mol of water.
  4. Number of water molecules = Avogadro constant x amount of substance in mol.

What is 0.5 mole mass?

Thus, the mass of 0.5 mole of water (H2O) is 9 grams.

How many particles are there in 3.6 mol of water?

A mole is the unit used to measure a group of 6.022×1023particles. 1 mole of any substance is equal to the atomic or molecular mass of that compound that is equal to these numbers of atoms. We have been given water that has a chemical formulaH2O with an amount of 3.6 g.

How many particles are there in 0.5 moles of sodium?

There are technically no molecules in 0.5 moles of sodium because sodium is not a diatomic element that can form a molecule with itself.

What is the mass of O 5 mole of water?

9g
The molecules of water have hydrogen bonding and thus, for another substance to be soluble in water molecules shall form hydrogen bond with water. Mass of 0.5 mole of water is 9g.

What is the basicity of aluminium sulphate?

Aluminium sulphate has zero basicity whereas that of the polymerized aluminium salts varies from about 50\% for Al 2 (OH) 3 Cl 3 (i.e. 10\% w/w Al 2 O 3) to about 85\% for ACH (24\% w/w Al 2 O 3 ). The H + ions produced by aluminium sulphate, PACl (10\% w/w Al 2 O 3) and ACH are 6, 3 and 1, respectively.

How many moles of oxygen are in 1 mole of aluminium sulphate?

Now the chemical formula of aluminium sulphate is Al2 (SO4)3. It shows that 1 mole of this compound contains 12 moles of oxygen atoms. So for 0.6 moles of oxygen atoms, the required number of moles of aluminium sulphate is= (0.6 / 12)=0.05 .

How many molecules of Al2O3 are present in 102G of aluminium oxide?

Calculate the number of aluminium ions present in 0.051 g of aluminium oxide. Solution: Mole of aluminium oxide (Al 2 O 3) = 2 x 27 + 3 x 16 = 102 g. i.e., 102 g of Al 2 O 3 = 6.022 x 1023 molecules of Al2O3. Then, 0.051 g of Al 2 O 3 contains = 6.022 x 10 23 / 102 x 0.051 molecules. = 3.011 x 10 20 molecules of Al 2 O 3.

What is aluminium sulfate (Anh)?

aluminium sulfate (anh.) Anhydrous aluminum sulfate is a white crystalline solid. Aluminum sulfate is also obtained as an 18-hydrate Al2 (SO4)3.18H2O. Both forms are soluble in water, noncombustible, and nontoxic. The primary hazard is the threat to the environment. Immediate steps should be taken to limit its spread to the environment.
