What is the mathematical formula for Coulomb’s Law in a vacuum?

The formula is F = (1/4πε₀) * (q₁q₂/r²), where ε₀ is the permittivity of free space.

What is the value of the electrostatic constant k?

The approximate value of k is 9 × 10⁹ N m² C⁻².

Under what conditions is Coulomb’s Law valid?

It is strictly valid for stationary charges and point charges (where size is much smaller than the distance).
