Fossils of single-celled organisms have been recovered from rocks as old as 3.5 billion years. Animal fossils first appear in rocks dating back about 1 billion years.
Explanation:
The product of molarity and volume of any substance at a fixed temperature is constant. Therefore comparing two portions of different molarity, we can say that, M₁V₁=M₂V₂
M represents the molarity, V represents volume of the solution.
M₁ in the question is 8.8M
M₂ is 2.2M
V₁=?
V₂= 175
therefore,
8.8ₓV₁= 2.2ₓ175ml
V₁=(2.2ₓ175ml)/8.8
=43.75 ml
