Isotopes are atomic elements with the same proton number. The atomic number of the Ru atom in the periodic table will be 44 and the mass will be 100.9.
<h3>What are atomic numbers and mass?</h3>
Atomic numbers are the number of protons present in the nucleus of the atom. Whereas the atomic mass is the total number of protons and the neutrons of the atom.
The atomic number is the number of protons and remains constant for the same element at different places or planets. Hence, the atomic number of Ruthenium will be 44.
The atomic mass depends on the relative abundance and is calculated as:

Therefore, the atomic mass of Ru is 100.9 and the atomic number is 44.

Answer:
The volume of the gas is determined, which will allow you to calculate the temperature.
Explanation:
According to Charles law; the volume of a given mass of an ideal gas is directly proportional to its temperature at constant pressure.
This implies that, when the volume of an ideal gas is measured at constant pressure, the temperature of the ideal gas can be calculated from it according to Charles law.
Hence in the Ideal Gas Law lab, the temperature of an ideal gas is measured by determining the volume of the ideal gas.
Vascular tissue transports water, minerals, and sugars to different parts of the plant. Vascular tissue is made of two specialized conducting tissues: xylem and phloem. Xylem tissue transports water and nutrients from the roots to different parts of the plant, and also plays a role in structural support in the stem.
