Azero-order reaction has a constant rate of 4.40×10−4 m/s. if after 45.0 seconds the concentration has dropped to 1.50×10−2 m, what was the initial concentration? express your answer with the appropriate units.

We have that the initial concentration  is mathematically given as

1 * {10}^{-11} M

Generally the equation for the PH  is mathematically given as

Therefore

1 * {10}^{-11} M
