A flask contains 3.2 g of sulphur dioxide. Calculate the followings:
i) The number of molecules of sulphur dioxide at STP.
ii) The volume occupied by 3.2 g of sulphur dioxide at STP.
(S = 32, O = 16)
Calculate the mass of (i) 1022 atoms of sulphur, (ii) 0.1 mole of carbon dioxide.
[Atomic mass: S = 32, C = 12 and O = 16 and Avogadro's Number = 6 × 1023]
What is the mass of 18.066 × 1023 molecules of carbon dioxide?
