Alkali metals are known as the group 1 elements.
When we know this, we just have to look to group 1 of the periodic table.
Rb (Rubidium) is in group 1; it is classified as an alkali metal.

Answers
The concentration of a solution can be expressed in (4) moles per liter
Further explanation
Stoichiometry in Chemistry learn about chemicals mainly emphasizes quantitative, such as the calculation of volume, mass, number, which is related to numbers, molecules, elements, etc.
In the reaction there are also manifestations of reagent substances namely gas (g), liquid (liquid / l), solid (solid / s) and solution (aqueous / aq).
The concentration of a substance can be expressed in several quantities such as moles, percent (%) weight / volume,), molarity, molality, parts per million (ppm) or mole fraction. The concentration shows the amount of solute in a unit of the amount of solvent.
- Kelvin
Temperature is used as a guide to the level of heat energy from objects
Temperature cannot be measured by the surface of the hand because it is not accurate but can be measured by a thermometer. Temperature units include Celsius, Fahrenheit, Reamur or Kelvin
- milliliters
Volume is a derivative quantity derived from the length
The unit of volume can be expressed in liters or milliliters or cubic meters
- joules per kilogram
Energy can be interpreted as the ability to do work
Energy units can be stated in joules or calories (J or Cal)
- moles per liter
Mole
The mole itself is the number of particles contained in a substance amounting to 6.02.10²³
Mole is the result of dividing the amount of substance mass and its molar mass
Molarity is a way to express the concentration of the solution
Molarity shows the number of moles of solute in every 1 liter of solute or mmol in each ml of solution
Where
M = Molarity
n = Number of moles of solute
V = Volume of solution
So to find the number of moles can be expressed as
n = V x M

(2) -120.°C (4) +393°C
Answers
Therefore, if we subtract 273, we get the temperature in degrees
120 - 273 = - 153
Therefore, the answer is (1), or -153 degrees Celsius
Hope this helped!! :D
Final answer:
The temperature 120 K converts to -153°C. This conversion is made by subtracting 273.15 from the Kelvin temperature.
Explanation:
To convert Kelvin (K) to Celsius (°C), you subtract 273.15 from the Kelvin temperature. For example, 120 K becomes 120 - 273.15, equaling -153.15°C. Rounded, this is approximately -153°C. It's essential to note that 0 K is absolute zero, representing the lowest possible temperature, which corresponds to -273.15°C on the Celsius scale. Therefore, the correct answer is (1) -153°C. This conversion is fundamental in relating temperatures on the Kelvin and Celsius scales, where Celsius measures temperature relative to the freezing and boiling points of water, and Kelvin starts from absolute zero, the absence of thermal energy.
