For reference, the ideal gas law is
.
![\frac{P_0V_0}{PV} =\frac{n_0RT_0}{nRT}](https://tex.z-dn.net/?f=%5Cfrac%7BP_0V_0%7D%7BPV%7D%20%3D%5Cfrac%7Bn_0RT_0%7D%7BnRT%7D)
(Variables with a subscript of 0 are the values at 45°C and variables without a subscript are the values at 70°C.)
Assuming constant pressure:
![V=\frac{V_0T_0}{T} =\frac{(8.5 \text{ L})(45 \text{{\textdegree}C})}{70 \text{{\textdegree}C}} =5.464 \text{ L}](https://tex.z-dn.net/?f=V%3D%5Cfrac%7BV_0T_0%7D%7BT%7D%20%3D%5Cfrac%7B%288.5%20%5Ctext%7B%20L%7D%29%2845%20%5Ctext%7B%7B%5Ctextdegree%7DC%7D%29%7D%7B70%20%5Ctext%7B%7B%5Ctextdegree%7DC%7D%7D%20%3D5.464%20%5Ctext%7B%20L%7D)
The number with the least significant figures is 70 (1 s.f.), so with correct significant figures, the volume would be 5 L.
The magma in the mantle layer moves, and while it's moving the plates move as well, forming mountains, volcanoes, ridges, etc.
Answer:
The mass of an empty graduated cylinder is 72.57 g, the volume of water is 50 mL, the mass of graduated cylinder and water is 122.38 g.

Explanation:
Electron affinity is defined as the change in energy (in kJ/mole) of a neutral atom (in the gaseous phase) when an electron is added to the atom to form a negative ion. In other words, the neutral atom's likelihood of gaining an electron.
The electron affinity values of the following elements is given;
Electron Affinity of Hydrogen is 72.8 kJ/mol.
Electron Affinity of Lithium is 59.6 kJ/mol
electron affinity of carbon is 153.9 kJ mol‑1
Electron Affinity of Fluorine is 328 kJ/mol
The electron affinity of neon is 0 kJ mol‑1.
When nonmetals gain electrons, the energy change is usually negative because they give off energy to form an anion (exothermic process); thus, the electron affinity will be negative.
Nonmetals have a higher electron affinity than metals, meaning they are more likely to gain electrons than atoms with a lower electron affinity.
That explains why florine seems to have the highest electron affinity value.
