CSEC Chemistry · May/June 2011 · Paper 1 · Question Q10
Which of the following compounds has the GREATEST percentage by mass of carbon present in one mole? (M_r = \text{relative molecular mass}; relative atomic mass: \text{H} = 1; \text{C} = 12; \text{O} = 16)
- (A)
\text{C}_2\text{H}_4\text{O}_2(M_r = 60) - (B)
\text{C}_3\text{H}_8\text{O}(M_r = 60) - (C)
\text{C}_2\text{H}_6\text{O}(M_r = 46) - (D)
\text{C}_6\text{H}_{12}\text{O}_6(M_r = 180)
