A harmonic oscillator has mass 0.530km and an ideal spring with force constant 146N/m .

Find the period, frequency, and angular frequency.

period is 2pisqr(m/k)

frequnecy is 1/t
I assume your mass units are kg, not km. Mikhail's period formula is correct.

The angular frequency (rad/s) is
sqrt(k/m) and the actual frequency is that divided by 2 pi
