Answer:
[tex]\mathbf{C_4 H_{8}O_{4}}[/tex]
Explanation:
From the given information:
Assume the molecular formula to be: [tex]C_a H_{2a} O_{a}[/tex]
Then, the molecular mass will be = 12a + 2a + 16a = 30a (since the C = 12, H = 2 & O = 16) respectively.
Thus;
30a = 120
a = 120/30
a = 4
Thus, the molecular formula:
[tex]=C_4 H_{2*4} O_{4}[/tex]
[tex]= \mathbf{C_4 H_{8}O_{4}}[/tex]
