Answer:
150000.5
Step-by-step explanation:
300000 x 2000000= 600000000000
600000000000 + 2000000= 600002000000
600002000000/ 4000000= 150000.5
To find the number of half lives divide the total number of days by the number of days for 1 half live:
1104 / 138 = 8
There are 8 half lives.
To find the total amount left multiply the starting amount by 1/2 to the 8th power:
38 * 0.5^8 = 0.148 = 0.15 grams
The answer is the last one.
