The Hubble constant, H0, is approximately 73 km/(s × Mpc). This value is given in mixed units because it uses both kilometers and megaparsecs, which both measure distance. Multiplying this value by the conversion factor (1 Mpc)/(3.086 × 1019 km) fixes this issue. What is the resulting value for the Hubble constant? Write your answer in scientific notation. Be sure to include simplified units.
