The number of millimoles of .(6)^(14)C ...

The number of millimoles of `._(6)^(14)C` equivalent to one millicuires if `t_(1//2) = 5770` year and `1` curie `= 3.7xx10^(10)` dps is:

A

`1.56xx10^(-2)`

B

`3.12xx10^(-2)`

C

`4.34xx10^(-2)`

D

`7.80xx10^(-2)`

Text Solution

Verified by Experts

The correct Answer is:
`(a)`
1 milli curie `= 3.7xx10^(10)xx10^(-3)` dps
`:. r = lambda.N`
or `3.7xx10^(7) = (0.693)/(5570xx365xx24xx60xx60) xx N`
`:. N = 9.38xx10^(18)`
`:.` Mole of `._(6)^(14)C = 1.56xx10^(-2)`
