Answer 2

Number of Atoms and Molecules in 4 kg of SO3

To determine the number of atoms and molecules in 4 kg of SO3, we need to use the molar mass of SO3 and Avogadro's number.

1. Calculate the molar mass of SO3: - The molar mass of sulfur (S) is approximately 32.06 g/mol. - The molar mass of oxygen (O) is approximately 16.00 g/mol. - Since SO3 consists of one sulfur atom and three oxygen atoms, the molar mass of SO3 is: Molar mass of SO3 = (1 * molar mass of S) + (3 * molar mass of O) = (1 * 32.06 g/mol) + (3 * 16.00 g/mol) = 32.06 g/mol + 48.00 g/mol = 80.06 g/mol.

2. Calculate the number of moles in 4 kg of SO3: - We know that 1 mole of any substance contains Avogadro's number of particles, which is approximately 6.022 x 10^23. - To calculate the number of moles, we can use the formula: Moles = Mass / Molar mass Moles of SO3 = 4000 g / 80.06 g/mol = 49.95 mol.

3. Calculate the number of atoms in 4 kg of SO3: - Since 1 mole of SO3 contains Avogadro's number of molecules, we can calculate the number of molecules in 49.95 moles of SO3: Number of molecules = Moles of SO3 * Avogadro's number = 49.95 mol * 6.022 x 10^23 molecules/mol = 3.007 x 10^25 molecules.

- Since each SO3 molecule contains 1 sulfur atom and 3 oxygen atoms, we can calculate the number of atoms in 3.007 x 10^25 molecules of SO3: Number of atoms = Number of molecules * (1 sulfur atom + 3 oxygen atoms) = 3.007 x 10^25 molecules * (1 + 3) = 3.007 x 10^25 molecules * 4 = 1.203 x 10^26 atoms.

Therefore, in 4 kg of SO3, there are approximately 49.95 moles, 3.007 x 10^25 molecules, and 1.203 x 10^26 atoms of SO3
