A 48g sample of Germanium-66 is left undisturbed for 10 hours. At the end of that period, only remain. What is the half-life of this material?

#12 the answer is the third option

hello 0xxbadwolfxx0,

2.6 x 10^9 is 2,600,000,000.

1.3 x 10^2 is 130

multiplying 130 and 2,600,000,000 would simply give you 200,000,000,000.

therefore, the answer would be d. 2.0 × 10^11.

i hope i ! warm regards, mae.
