Question

Which of the following represents 32g of the substance? (1) 1 g atom of sulphur (2) 22.4 L of O2 gas at STP (3) One mole of oxygen atoms (4) One mole of sulphur molecules (A) 1, 2 and 3 are correct (B) 1 and 2 are correct (C) 2 and 4 are correct (D) 1 and 3 are correct

Tardigrade Admin · Accepted Answer

One gram atom of sulphur = 32 g 22.4 L O2 at STP = 1 mol = 32 g One mole oxygen atoms = 16 g One mole of S8 molecules =8× 32=256g.

Q. 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 molecules

1, 2 and 3 are correct

1 and 2 are correct

2 and 4 are correct

1 and 3 are correct

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
$= 8 \times 32 = 256 g .$
