How much of a 1.0 g polonium-214 sample remains after 818 microseconds? The half life of polonium -214 is 163.7 microseconds

0.3125g

Step-by-step explanation: 1.0 * 1/2= 0.5

0.5* 1/2= 0.25

0.25* 1/2= 0.125

0.125* 1/2= 0.625

0.625* 1/2= 0.3125g

0.0320g

Step-by-step explanation:

solving for M, and we are given Mo=1.00g, t=818 microseconds, t1/2=163.7 microseconds.

n=t/t1/2=818/163.7=4.97

M=Mo(1/2)n=1.00(1/2)4.97=0.0320g

school a:

minimum value is 2

maximum value is 22

the lower quartile is 2.5

the median is 10

the upper quartile is 15.5

school b:

minimum value is 9

maximum value is 20

the lower quartile is 12

the median is 16

the upper quartile is 18

box plot for school a isn't symmetrical. the data tails on the right

box plot for school b isn't symmetrical. the data tails on the left

we would need a picture of the quadrilateral in order to answer the question. also, it seems that the question is missing some components.
