Which of the following represents 32g of the substance? (1) 1 g atom of sulphur (2) 22.4 L of\[{{O}_{2}}\]gas at STP (3) One mole of oxygen atoms (4) One mole of sulphur moleculesA) 1, 2 and 3 are correct
B) 1 and 2 are correct
C) 2 and 4 are correct
D) 1 and 3 are correct
Correct Answer: B
Solution :
One gram atom of sulphur = 32 g 22.4 L\[{{O}_{2}}\]at STP = 1 mol = 32 g One mole oxygen atoms = 16 g One mole of\[{{S}_{8}}\]molecules\[=8\times 32=256g.\]
