Question

question 21 (1 point) the number of molecules contained in 22.4 l of an ideal gas at stp is not one mole 96 400 avogadros number 6.02 x 10^23

Explanation:

Step1: Recall molar volume at STP

At standard - temperature and pressure (STP), the molar volume of an ideal gas is 22.4 L/mol. This means that 1 mole of an ideal gas occupies 22.4 L at STP.

Step2: Recall Avogadro's number

One mole of any substance contains Avogadro's number of particles (atoms, molecules, etc.). Avogadro's number is \(6.02\times 10^{23}\) particles/mol. So, the number of molecules in 22.4 L of an ideal gas at STP (which is 1 mole) is \(6.02\times 10^{23}\).

Answer:

\(6.02\times 10^{23}\)
