The atomic mass of Carbon is 12 while that of Oxygen is 16.
Given that the molecular mass of the compound is 290 and that 50% by mass is carbon and oxygen, we can form the following equations,
Let the no. of Carbon atoms be X and the no. of Oxygen atoms be Y.
From the above data, the following can be concluded,
12 X = 290/2
=> X =145/12
=> X = 12.08
Similarly,
16Y = 290/2
=> Y = 145/16
=> Y = 9.06
C12O9
is the molecular formula of the given compound.
