define the following write the units and formula
The formula for energy. E is for energy(Units = Joules) P is for power(Units = Watts) T is for time(Units = Seconds)
Torque is measured as a unit of length times a unit of force, so the SI unit is Newton-meters (Newton times meters). Imperial units would probably be something like foot-pound. Note that this is unrelated to energy units, also measured in Newton-meters. The unit "joule" as an equivalent for Newton-meters is only used for energy units, not for torque units.
Density = Mass/Volume. Conversion between units will depend on what the two units are.
Formula for finding the surface area of a sphere = 4*pi*radius2 in square units. Formula for finding the volume of a sphere = 4/3*pi*radius3 in cubic units. Or did you mean the formula for finding the area of a square? in which case it is Length*Height in square units.
Newton-Meters
Dimensional formula of torque = [ML2T-2 ]

How many grams of NaCl are present in 8.39x10^22 formula units of NaCl?
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".
