Answer:
9.7 ml
Explanation:
Molarity = 2.5 M
Mass = 0.97g
Volume = ?
The relationship between these quantities is;
Molarity = Number of moles / Volume
Number of moles = Mass / Molar mass
Molar mass of NaOH = 40g/mol
Number of moles = 0.97 / 40 = 0.02425 mol
Volume = Number of moles / Molarity = 0.02425 / 2.5 = 0.0097 L
1000 ml = 1L
x = 0.0097 L
x = 0.0097 * 1000 = 9.7 ml

Answer: Either A or D
Geologists and paleontologists constructed the geologic table based on the relative positions of different strata and fossils, and estimated the time scales based on studying rates of various kinds of weathering, erosion, sedimentation, and lithification.
