Curium-243 has a half-life of 28.5 days. In a sample of 5.6 grams of curium-243, how many grams will remain after 12 days?

quester [9]

Answer:

C.4.18g

The amount will remain after 12 days is 4.18 g

Step-by-step explanation:

we can use formula

$P(t)=P_0(\frac{1}{2})^{\frac{t}{h} }$

where

h is half life time

t is time in days

Po is initial quantity

P(t) is the quantity after t days

we are given

Curium-243 has a half-life of 28.5 days

$h=28.5$

In a sample of 5.6 grams of curium-243

so,

$P_0=5.6$

now, we can plug values

$P(t)=5.6(\frac{1}{2})^{\frac{t}{28.5} }$

now, we can plug t=12

$P(12)=5.6(\frac{1}{2})^{\frac{12}{28.5} }$

$P(12)=4.18253$

So,

The amount will remain after 12 days is 4.18 g
