I understand that rate constants and rates are involved with the problem, but I'm not sure how to approach it..

**DrBob222**, Saturday, January 29, 2011 at 8:53pmI believe you want to use

ln(No/N) = kt.

Substitute No = 240

N = 240-11 = ??

t = 10 seconds.

Solve for k.

Then use k in

ln(No/N) = kt

No = 240-145 = ??

N = unknown

you know k and t. Solve for N, which will be number of kernals remaining; therefore, No-N must be the amount popped. Check my thinking.
