Question

Calculate the No. of molecules present in 11.5 dm3 of
NST​

Answer 1

Answer:

Answer: We know that, at standard temperature and pressure, 1 mole of any gas at STP contains 22.4 L of it. Therefore 11.5 liters of hydrogen(H2) is (1/22.4)*11.5 moles = 0.51 moles of hydrogen gas. We know that in 1 mole there is 6.022 × 10^23 molecules.
