A radioactive sample has a half life 1500 years. A sealed tube conataining 1g of the sample will contain after 3000 years,

A

1g of the sample

B

0.5g of the sample

C

0.25 g of the sample

D

0.00 g of the sample

Text Solution

Verified by Experts

The correct Answer is:
C
`T= t_(1//2) xx n , therefore 3000 = 1500 xx n therefore n = 2 `
`therefore` Amount left `= 1/(2^2) = 1/4 = 0.25 g `
