Themolar massMis a physical property. It is defined as the mass of a given substance divided by its amount, and its SI units are kgmol−1. The termrelative molar mass(RMM) is also used. This is defined as “the average mass of the molecule divided by 1/12 of the mass of an atom...
Density, mass per unit volume of a substance. The formula for density is d=M/V, where d is density, M is mass, and V is volume. Density is commonly expressed in units of gram per cubic centimeter. For example, the density of water is 1 gram per cubic cen
Most MS data are presented in units of mass-to-charge ratio, or m/z, where m is the molecular weight of the ion (in daltons) and z is the number of charges present on the measured molecule. For small molecules (<1000 Da) there is typically only a single charge and therefore the ...

with multi-joint exercises coded for the muscle group that is predominantly trained. RT volume was preferentially expressed in total tonnage (number of repetitions × number of sets × intensity load; kg) or, when not applicable, in weekly sets/muscle group. In the event that informati...
where Nin is the quantity of the sample molecule flowing into the computation domain during a period Δ Nin* is its dimensionless form. N*in = Nin / C0H3; Ain is the cross section area at the inlet of computational domain. Δt is the duration that the released sample Nin reaches a giv...
What is the mass concentration (in mg/mL) of glucose, {eq}C_6H_{12}O_6{/eq}, if 18 g of glucose is dissolved in 300 mL of water? Unit Conversion Unit conversion is used when we need to express a measurement from one unit to another....
