Answer:
It takes 27 minutes for the element to decay to 35 grams
Step-by-step explanation:
Given:
Initial amount  =  790 grams
Final amount = Â 35 grams
Half life = Â 6 minutes
To find:
Time taken for the element to reduce into 35 grams  = ?
Solutions
Time taken = [tex]half life \times \frac{ log(\frac{ initial amount}{final amount})}{log(2)}[/tex]
On substituting the values given, Time taken Â
= [tex]6 \times \frac{log(\frac{790}{35})}{log(2)}[/tex]
= [tex]6 \times \frac{log(22.57)}{log(2)}[/tex]
= [tex]6 \times 4.496[/tex]
= 26.97
= 27 minutes
Answer:
16.8 minutes
