1st half life: 195/2 = 97.5 g
2nd half life: 97.5/2 = 48.75 g
3rd half life: 48.7/2 = 24.375 g
4th half life: 24.375/2 = 12.1875 g
5th half life: 12.1875/2 = 6.09375 g
or you can do
195(2)^(-5) = 6.09375
** rounded to nearest gram = 6 g
Equation: <span>5/7d=2/3
Work:
5d/7 = 2/3
5d = 2/3 x 7
5d = 14/3
d = 14/3/5
d = 14 / 3 x 5
d = 14/15
Final Answer:
14/15 or 0.933333
