A cosmological model of the expansion of the universe yields a Hubble constant of H0=2.3×10−18 s−1H_0 = 2.3 \times 10^{-18}\text{ s}^{-1}H0​=2.3×10−18 s−1.

What is the value of this Hubble constant in units of km s−1 Mpc−1\text{km s}^{-1}\text{ Mpc}^{-1}km s−1 Mpc−1?

Given: 1 parsec=3.09×1016 m1\text{ parsec} = 3.09 \times 10^{16}\text{ m}1 parsec=3.09×1016 m
