The remaining amount of the sample after 't' days would be 51. 74g

<h3>How to determine the amount</h3>

We have the formula for amount to be;

A = Ao × (1/2)^ t/t^1/2

Where

t1/2 = half -life = 138 days

t = 1

Ao = 52g

A = Amount after decay

Substitute into formula

A = 52 × (1/2) ^ 1/138

A = 52 ×

${ \frac{1}{2} }^{0.00724}$

A = 52 × 0. 9950

A= 51. 74 g

Thus, the remaining amount of the sample after 't' days would be 51. 74g
