<span>This is the process of radioactive dating. Carbon is used because it is an essential part of all living organisms and has a radioisotope that decays with a half-life of 5000 years. This ratio makes it easy to date an object using Carbon-14. Uranium is used for objects that have a much longer half-life, outside the bounds of carbon's abilities.</span>
Answer:
LiHe is a compound of helium and lithium. The substance is a cold low density gas made of molecules each composed of a helium atom and lithium atom bound by van der Waals force.
Answer:
The right answer is V = 17.2 mL
Explanation:
- Knowing that the the relation between No. of moles and concentration:
No. of moles = C * V
where,
C is the concentration in morality and
V is the volume in liter
so you can calculate the volume using:
V = (No. of moles / C) = (0.0131 mol / 0.763 mol/L)
V = 0.0172 L
- Then yo need to convert the volume from Liter to milliliter
V = 0.0172 L * (1000 mL / 1 L)
V = 17.2 mL
So, the right answer is V = 17.2 mL
