Question #cff1c

Answer 1

32 days =4x8 days, so it means 4 halvings.

Explanation:

`1/2xx1/2xx1/2xx1/2=1/16`

So the remaining part will be:

`1/16xx0.0024g=0.00015g`

Note:
If we had used the metric prefixes, it would have been a bit easier (without all the zeroes):

`0.0024g=2.4mg->1/16xx2.4mg=0.15mg`
