The hlaf - life of `""_(84)^(209)P_0` is 103 Years. The time is takes for 100 g sample of `""_(84)^(209)P_0` to decay to 3.125 g is

A

3296 years

B

`103 sqrt2` years

C

1648 years

D

515 years

Text Solution

Verified by Experts

The correct Answer is:
D

In one half life , half of amount is decayed so , decay occurs as,

so time taken ` = 103 xx 5 = 515 yr `
