The half-life period of a radioactive substance is 8 years. After 16 y

1.	The half-life period of a radioactive substance is 8 years. After 16 years, the mass of the substance will reduce from starting 16.0 g toA. 8.0 gB. 6.0 gC. 4.0 gD. 2.0 g
Answer» Correct Answer - C `n = (16)/(8) = 2, N = (N_(0))/(2^(n)) = (16.0)/(2^(2)) = (16.0)/(4) = 4.0 g`
