<span> In this question (t½) of C-14 is 5730 years, which means that after 5730 years half of the sample would have decayed and half would be left as it is. After 5730 years ( first half life) 70 /2 = 35 mg decays and 35 g remains left. After another 5730 years ( two half lives or 11460 years) 35 /2 = 17.5mg decays and ...</span>Missing: <span>25g</span>
Answer:
Explanation:
The dilution formula is
s₁ v₁ = s₂ v₂
s₁ = .0043
v₁= 2 mL
v₂ = 100 mL
s₂ = ?
putting the values
.0043 x 2 = s₂ x 100
s₂ = .000086 = 86.0 x 10⁻⁶
