GaryK [48]

Answer:

4 grams

Explanation:

A = A₀e^⁻kt

A₀ = 125.0 grams

k= 0.693/t(1/2) = (0.693/68.8) yrs⁻¹ = 0.01 yrs⁻¹

t = 344.0 years

A = 125.0g·[e^-(0.01yrs⁻¹)(344.0yrs)] = 125(0.032)grams = 4.000g (4 sog. figs. based on A₀ = 125.0 grams)

once we’ve done this, we can plug in the numbers:
(800•500) = (200•V2)
and then we get that
V2= 2000 ml

hope this helps!! :)
