Find the expression for the mass

The rate of decay in the mass, M, of a radioactive substance is given by the differential equation dM dt equals negative 1 times k times M, where k is a positive constant. If the initial mass was 200g, then find the expression for the mass, M, at any time t.

Question options:

1) M = 200ln(kt)

2)  M = 2e-kt

3)  M = 200 ekt

4)  M = 200 e-kt
