Two capacitors with electrical capacity C1 = 3 μF and C2 = 6 μF are connected in series in an alternating current circuit with voltage U = 220V and frequency v = 50Hz. Determine the current I in the circuit.

Let E – an unknown element, and EO2 – its higher oxide (since the element is in the IV-th group).

By condition, the relative density of EO2 for oxygen:

DO2 (EO2) = M (EO2) / M (O2) = 2.5,

M (EO2) / M (O2) = 2.5,

(M (E) + 16 * 2) / (16 * 2) = 2.5,

M (E) = 48 (amu), which corresponds to the element titanium (Ti).

Answer: titanium (Ti).
