What is the RFM of Al(OH)₃?

[frigid wagon]

The molecular formula of aluminum hydroxide is Al(OH)₃. The molar mass of aluminum (Al) is 26.98 g/mol, and the molar mass of oxygen (O) is 16.00 g/mol. The molar mass of hydrogen (H) is 1.01 g/mol.

To calculate the relative formula mass (RFM) of Al(OH)₃, we need to add up the molar masses of all the atoms in the formula using their respective subscripts.

RFM = (Atomic mass of Al) + (Atomic mass of O) × 3 + (Atomic mass of H) × 3
RFM = (26.98 g/mol) + (16.00 g/mol) × 3 + (1.01 g/mol) × 3
RFM = 101.96 g/mol

Therefore, the RFM of Al(OH)₃ is 101.96 g/mol.

number of atoms in 17g of amonia

[frigid wagon]

To determine the number of atoms in 17 grams of ammonia (NH₃), we need to use Avogadro's number, which states that there are approximately 6.022 × 10²³ particles (atoms, molecules) in one mole of a substance.

First, we calculate the number of moles of ammonia:

Number of moles = Mass in grams / Molar mass
Number of moles = 17 g / (14.01 g/mol + 3 * 1.008 g/mol)
Number of moles = 17 g / 17.03 g/mol
Number of moles ≈ 0.998 moles

Now, we can use Avogadro's number to determine the number of atoms:

Number of atoms = Number of moles × Avogadro's number
Number of atoms ≈ 0.998 moles × 6.022 × 10²³ atoms/mol
Number of atoms ≈ 6.018 × 10²³ atoms

Therefore, there are approximately 6.018 × 10²³ atoms in 17 grams of ammonia.

To determine the number of atoms in 1 gram of hydrogen (H), we need to use Avogadro's number, which states that there are approximately 6.022 × 10²³ particles (atoms, molecules) in one mole of a substance.

First, we calculate the number of moles of hydrogen:

Number of moles = Mass in grams / Molar mass
Number of moles = 1 g / 1.01 g/mol
Number of moles ≈ 0.99 moles

Now, we can use Avogadro's number to determine the number of atoms:

Number of atoms = Number of moles × Avogadro's number
Number of atoms ≈ 0.99 moles × 6.022 × 10²³ atoms/mol
Number of atoms ≈ 5.99 × 10²³ atoms

Therefore, there are approximately 5.99 × 10²³ atoms in 1 gram of hydrogen.

number of atoms in 56 gram of iron

[frigid wagon]

To determine the number of atoms in 56 grams of iron (Fe), we need to use Avogadro's number, which states that there are approximately 6.022 × 10^23 particles (atoms, molecules) in one mole of a substance.

First, we calculate the number of moles of iron:

Number of moles = Mass in grams / Molar mass
Number of moles = 56 g / 55.85 g/mol
Number of moles ≈ 1.002 moles

Now, we can use Avogadro's number to determine the number of atoms:

Number of atoms = Number of moles × Avogadro's number
Number of atoms ≈ 1.002 moles × 6.022 × 10^23 atoms/mol
Number of atoms ≈ 6.03 × 10^23 atoms

Therefore, there are approximately 6.03 × 10^23 atoms in 56 grams of iron.
