Density is defined as mass per unit volume. It has the SI unit kg m-3 or Kg/m-3 and is an absolute quantity. Specific gravity is the ratio of a material's density with that of water at 4 °C (where it is most dense and is taken to have the value 999.974 kg·m-3). It is therefore a relative quantity with no units.
The period is simply the inverse of the frequency, therefore:
T = 1 / f
T = 1 / 775 Hz
T = 0.001290 s → possible answer
T = 1.29 × 10⁻³ s → possible answer
T = 1.29 ms → possible answer
