Which of the following figures does not represent 1 mole of dioxygen gas at STP?
A. 16 grams of gas
B. 22.7 litres of gas
C. 6.022 × 1023 dioxygen molecules
D. 11.2 litres of gas
We know, at STP (273K, 1 atm), 1 mole of any substance will contain Avogadro number of molecules, which is 6.023×1023 and if it is a gas, it will occupy a volume of 22.4L. Also, molar mass of oxygen gas (O2) is 32gm.
So, (ii) and (iii) are correct statements, but in the question, it is mentioned to find the incorrect options, so (i) and (iv) are the incorrect facts.
