The formation of sulphur trioxide (𝑺𝑶𝟑 )is represented by the following balanced
equation:
Identify the element in the above equation.
Draw the Lewis dot diagram of the oxygen molecule (𝑶𝟐 ). (2)
During the above reaction, 𝟏𝟎 g 𝑶𝟐 reacts completely with sulphur dioxide (𝑺𝑶𝟐 ).
Calculate the:
Number of moles of 𝑶𝟐 reacted. (3)
, Theoretical yield of 𝑺𝑶𝟑 , in grams. (4)
Percentage yield if 𝟒𝟎 gof 𝑺𝑶𝟑 is produced at the end of the reaction. (3)

An inorganic compound has the following percentage composition: 43,39% sodium
(Na), 11,32% carbon (C) and 45,28% oxygen (O).
Determine the empirical formula of this compound. (5)
Assume a 100 g sample:
Element Mass (g) Calculation Mole ratio Simplest ratio
Na 43,39 (43,39 \div 23) 1,8867 2
C 11,32 (11,32 \div 12) 0,9433 1
O 45,28 (45,28 \div 16) 2,83 3
Divide all the mole values by the smallest value, 𝟎, 𝟗𝟒𝟑𝟑:
Therefore, the empirical formula is:
