Question

calculate the number of molecules in 1dm3cube of oxygen at S.T.P?​

Answer 1

Answer:

mole of H2 at STP occupy 22.4 dm3 1 mole of H2 = 22.4 dm3 =6.022 x 1023 molecules 22.4 dm3 of hydrogen contain molecules = 6.022 x 1023 1 dm3 of hydrogen contain molecules = 6.022X1023 /22.4 = 2.69 x 1022 moleculesRead more on Sarthaks.com - https://www.sarthaks.com/64217/calculate-the-number-of-molecules-present-in-1-dm-3-of-hydrogen-at-stp?show=64218#a64218
