calculate the volume occupied by 8gms of sulphur dioxide at stp
Calculate the volume of air at STP, required to convert 300 mL of sulphur dioxide to sulphur trioxide. Air contains 21% oxygen by volume.
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)
(a) Calculate the mass of nitrogen supplied to the soil by 5 kg of urea [CO(NH2)2] [O=16:N=14;C=12;H=1] (b) Calculate the volume occupied by 320 g of sulphur dioxide at STP [S=32;O=16]
