A mass of 2 units refers to a quantity of matter or material. In physics, mass is a measure of the amount of substance in an object, typically measured in units like kilograms or grams. So, 2 units of mass could represent any quantity depending on the specific unit being used.
This question needs clarification, because "formula units" can mean either the number of atoms to constitute one formula or Avogadro's Number of such formula units, although the latter should more precisely described as "gram formula units".
Cyclones of the southern hemisphere are measured by wind speed and assigned a category number. Whether or not they are classified as a cyclone is also determined by barometric pressure.Wind speeds determine the category as follows:Category 1: winds up to 125km/hCategory 2: 125- 170 km/hCategory 3: 170 - 225 km/hCategory 4: 225 - 280 km/hCategory 5: in excess of 280 km/hHurricanes, which are cyclones in the north-western hemisphere, are measured on the Saffir-Simpson scale. The categories are measured as follows:Tropical Storm - Winds 39-73 mphCategory 1 Hurricane - winds 74-95 mphCategory 2 Hurricane - winds 96-110 mphCategory 3 Hurricane - winds 111-130 mphCategory 4 Hurricane - winds 131-155 mphCategory 5 Hurricane - winds 156 mph and up
To calculate the number of moles, first find the molar mass of CaCl2 (40.08 g/mol for Ca + 2 * 35.45 g/mol for Cl). Then divide the given number of formula units by Avogadro's number (6.022 x 10^23 formula units/mol) to get the number of moles.
There isn't a SI unit particularly for this. It would just be expressed as so many parts per million, or sometimes chemists use mg/kg which would be the same thing, or mg/liter if dealing with liquids. The standard for measuring any quantity of atoms or molecules is the mole. It is not uncommon to see "linear ozone density" expressed in Dobson units, based on characteristic absorption on a path. Along the lines of the Beer Lambert law...
There are many instances: for example, speed is measured in kilometres per hour where the ratio is measured between a distance (measured in kilometres) and time (measured in hours). So it is no big deal except that you need to mention the units.

To measure kinetic energy:Let us suppose an object of mass m moving wtih velocity vKinetic Energy of that object= mv2/2
Because the perimeter is a linear measurement, and area is measured by multiplying 2 linear measurements together.
Area is measured in squared units, such as cm^2. One centimetre squared is a box that is 1cmx1cm. Perimeter is measured in normal units, such as centimetres.
Dimensionally, force divided by speed is [MLT-2] / [LT-1] = [MT-1].In SI units, it's (newton) / (meter per second) = Kilogram per second.That unit doesn't seem to have much physical significance, or to be too useful,unless maybe you're planning a career in residential coal delivery.
Pressure is typically measured in units such as Pascals (Pa), atmospheres (atm), or pounds per square inch (psi). Force is measured in units such as Newtons (N) or pounds (lbs), and area is measured in units such as square meters (m^2) or square inches (in^2).
Speed can be measured in units like meters per second (m/s), kilometers per hour (km/h), or miles per hour (mph). Velocity can be measured in the same units as speed. Acceleration can be measured in units such as meters per second squared (m/s^2) or centimeters per second squared (cm/s^2).
Square units measure area. It could be area of square, rectangle, triangle, curved surface area and total surface area etc.
The area of a sector is 0.5*r^2*theta square units where r is the radius measured in linear units and theta is the angle (measured in radians).

Angular acceleration is typically measured in units of radians per second squared (rad/s^2).
