32P has a half life of 14.0 days. If you order 60.0 grams of 32P and it took 46.7hrs from the time it was made to the time it wa

8090 [49]

Answer:

$[A_t]=54.5\ g$

Explanation:

Given that:

Half life = 14.0 days

$t_{1/2}=\frac{\ln2}{k}$

Where, k is rate constant

So,

$k=\frac{\ln2}{t_{1/2}}$

$k=\frac{\ln2}{14.0}\ days^{-1}$

The rate constant, k = 0.04951 days⁻¹

Initial concentration [A₀] = 60.0 g

Time = 46.7 hrs

Considering, 1 hr = 0.041667 days

So, time = 1.9458 days

Using integrated rate law for first order kinetics as:

$[A_t]=[A_0]e^{-kt}$

Where,

$[A_t]$ is the concentration at time t

So,

$[A_t]=60.0\times e^{-0.04951\times 1.9458}\ g$

$[A_t]=54.5\ g$
