If the sample is a protein, the mean residue weight ( average molecular weight of the amino acid residues it contains ) is often used in place of the molecular weight, essentially treating the protein as a solution of amino acids.

In this equation, " k " is a variable characterizing the chain length ( e . g . number average molecular weight, degree of polymerization ), and " a " is an empirically-determined constant.

The numbers that are often included in the names of PEGs indicate their average molecular weights ( e . g . a PEG with n = 9 would have an average molecular weight of approximately 400 daltons, and would be labeled PEG 400.

The scale height of the atmosphere is about, which is higher than Earth's,, because the surface gravity of Mars is only about 38 % of Earth's, an effect offset by both the lower temperature and 50 % higher average molecular weight of the atmosphere of Mars.

Polymers can be characterized by a variety of definitions for molecular weight including the number average molecular weight ( M n ), the weight average molecular weight ( M w ) ( see molar mass distribution ), the size average molecular weight ( M z ), or the viscosity molecular weight ( M v ).

Carrageenan in solution is processed at low pH ( ~ pH1.0 ) and high temperature ( ~ 90 �C / 194 �F ) for up to 6h until the weight-average molecular weight ( Mw ) has been reduced to the range 10, 000 20, 000 Daltons ( 10-20 kDa ).

Of course, the Hindenburg was inflated with hydrogen; with helium you get about 8 % less lift, so you need a slightly bigger airship for that reason . ( The calculation is ( 29-4 ) / ( 29-2 ) = 0.926, where 29, 4, and 2 are the respective average molecular weights of air, helium, and hydrogren .)
