1g radioactive element reduces to 1/3g after 2 days. After total 6 day

1.	1g radioactive element reduces to 1/3g after 2 days. After total 6 days how much mass will remain?choose the correct option from the given options. (A) 1/27 g (B)1/6 g (C) 1/9 g (D) 1/12 g
Answer» R,◆ Answer -(A) A2 = 1/27 g◆ Explanation -Amount of radioactive element at VARIOUS times is related as -A2/A0 = (A1/A0)^(t2/t1)A2/1 = (1/3)^(6/2)A2 = 1/3^3A2 = 1/27 gTherefore, after 6 days radioactive element will be 1/27 g.Thanks dear. HOPE this helps you..
