A Lab has a 500g sample of nitrogen. The substance has a half life of about 10 minutes.
Write a formula to express this.... I think I got this answer
V=500(250)^10
How much nitrogen is left after 30 min?
How much is left after an hour?
A Lab has a 500g sample of nitrogen. The substance has a half life of about 10 minutes.

How much nitrogen is left after 30 min?
How much is left after an hour?
the general equation for decay problem:
V=A(r)^n
A= sample start
r = rate of decay
n = period
in this case,
V=A(r)^n
A= 500
r = 0.5
n = 1 (1 = 10 minute)
how many after 30 minutes??
V=A(r)^n
A= 500
r = 0.5
n = 3 (1 = 10 minute)
how many after 1 hour???
(hint: you just convert hour to minute it would be the n)
....hope it help....
