WebApr 3, 2024 · MW is power, the rate of doing work. MWh is energy, how much total work can be done. To use a water analogy, MWh is the size of the water tank, MW is the size of the pipe going to the tank. Generally, larger tanks will have larger pipes, but that's not always the case. A small tank with a large pipe can fill and empty fast. WebSep 7, 2024 · The molecular weight of a particular polymer molecule is a product of the degree of polymerization and the molecular weight of the repeating unit.

WebKilowatt (symbol: kW) is a unit of electric power. Kilowatt definition Kilowatt examples kW to mW, W, MW, GW conversion calculator Kilowatt definition One kilowatt (kW) is equal to 1000 watts (W): 1kW = 1000W One kilowatt is defined as energy consumption of 1000 joules for 1 second: 1kW = 1000J / 1s One kilowatt is equal to 1000000 milliwatts: The molecular mass (m) is the mass of a given molecule: it is measured in daltons or atomic mass (Da or u). Different molecules of the same compound may have different molecular masses because they contain different isotopes of an element. The related quantity relative molecular mass, as defined by IUPAC, is the ratio of the mass of a molecule to the unified atomic mass unit (also known as the dalton) and is unitless. The molecular mass and relative molecular mass are …
Molecular weight is commonly abbreviated by M.W. or MW. Molecular weight is either unitless or expressed in terms of atomic mass units (amu) or Daltons (Da). Both atomic weight and molecular weight are defined relative to the mass of the isotope carbon-12 , which is assigned a value of 12 amu.
