The cylinder contains gas, the amount of the substance of which is 6 mol. How many (approximately) gas molecules are there in the bottle?

Initial data: ν (number of moles of gas in the cylinder) = 6 mol.

Constants: Na (Avogadro’s number) = 6.02 * 10 ^ 23 mol-1.

The number of gas molecules in the cylinder can be determined from the formula: ν = N / Na, whence N = ν * Na.

Let’s calculate: N = 6 * 6.02 * 10 ^ 23 = 36.12 * 10 ^ 23 molecules.

Answer: The cylinder contains 36.12 * 10 ^ 23 gas molecules.
