Half life is the amount of time it takes for a substance to reach half its initial point, right? Looking at the graph it shows that it initially started at 50 mg, 1/2 that is 25mg. From the graph, 25 mg was reached around 1 min., so the half life would be 1 min if I'm not mistaken.
That makes sense, Thank you! could you help me with just one more Q, its based on this graph to
Sure, go ahead.
When you are left with 6.25 mg of the radio active isotope, how many minutes would have passed from time equals zero?
Ohh, okay, it's asking how much time would if take for it to reach 6.25 mg from 50 mg at t=0. At t=0, it is 50 mg t=1 it is 25 mg at t=2 it is 12.50 mg at t=3 it is 6.25 at t=4 is it 3.125 So about 3 mins would have passed. Looking at the graph at t=3, it is a bit above half but between 0 and 10, so you could assume that's 6.25
I see what your talking about cx Thank you so much! (◡‿◡✿)
You're welcome (☞ﾟ∀ﾟ)☞
