At the beginning of an experiment, a scientist has 300 grams of radioactive goo. After 150 minutes, her sample has decayed to 37.5 grams. What is the half-life of the goo in minutes?



Find a formula for

G(t),

the amount of goo remaining at time T.

G=

How many grams of goo will remain after 32 minutes?

Half-life of the goo is 49.5 minutes

191.7 grams of goo will remain after 32 minutes

Step-by-step explanation:

Let denotes initial and final mass.

According to exponential decay,

Here, t denotes time and k denotes decay constant.

So, half-life of the goo in minutes is calculated as follows:

Half-life of the goo is 49.5 minutes

So,

Put

Put t = 32 minutes

your answer is b ^w^ hope i
