substance. It's useful in chemistry because it can be used to make chemically different molecules with different mass equal. It measures mass (the amount of matter in something), not "weight" meaning the gravitational pull on mass. Thus, in chemistry, it's acceptable to interchange weight ...
The relationship obtained can be used to calculate the Szigeti charge of alloys with intermediate composition.doi:10.1016/0022-3697(88)90222-3T.L. YeapA.K. KohElsevier LtdJournal of Physics & Chemistry of Solids
If each number (x) is assigned a corresponding positive weight (w), the weighted arithmetic mean is defined as the sum of their products (wx) divided by the sum of their weights. In this case, The weighted arithmetic mean also is used in statistical analysis of grouped data: each ...
(M=Vd), while the volume is equal to the mass divided by the density (V=M/d). Theweightof a body, which is usually of more practical interest than its mass, can be obtained by multiplying the mass by the acceleration ofgravity. Tables that list the weight per unit volume of ...
