A Compound Has The Molecular Formula X4O6 If 10 G Of X4O6 Has 5.72 G Of X, Then Find Atomic Mass Of X?

Molecular weight of compound \( X_{4}O_{6} \)

= 4 * X + 6 * 16

= 4X + 96.

Since\( (4X + 96)gm of \( X_{4}O_{6} \)contains X = 4a gm

Therefore, 10gm of \( X_{4}O_{6} \)contains

\( X = \frac{4a * 10}{4a + 96} \) \( \Rightarrow 5.72 = \frac{4a * 10}{4a + 96} \) \( \Rightarrow 22.88a + 549.12 = 40a \) \( \Rightarrow 17.12a = 549.12 \) \( \Rightarrow a = 32.07amu. \)

Therefore, the atomic mass of X is 32.07amu.
