An element with mass 290 grams decays by 13.2% per minute. how much of the
element is remaining after 14 minutes, to the nearest 10th of a gram?

40.0 grams

Step-by-step explanation:

An exponential decay function is

          .... (1)

where, a is initial value, t is time and r is decay rate.

It is given that element with mass 290 grams decays by 13.2% per minute.

Initial value = 290

Decay rate = 13.2% = 0.132

Substitute a=290 and r=0.132 in equation (1).

Substitute t=14 to find the amount of element remaining after 14 minutes.

Round the solution to the nearest tenth.

Therefore, element with mass 40.0 grams is remaining after 14 minutes.
