Calculate the relative formula mass (M) of FeSO_{4} Relative atomic masses: O=16; S=32; Fe=56.The relative formula mass (M) is ___ (b) What is the mass of one mole of iron(Ⅱ) sullate? Remember to give the unit. ___ (c...
1) (II) Calculate the relative formula mass of hydrogen chloride, hcl. (Relative atomic masses: h =
the formula mass may be correctly referred to as a molecular mass. Consider chloroform (CHCl3), a covalent compound once used as a surgical anesthetic and now primarily used in the production of the “anti-stick” polymer, Teflon. The molecular ...
Deconvolution (c) of the low molar mass portion of the peak using Gaussian components (thick grey line represents best fit) allows estimation of the relative mass fractions of each structure (e), which are in good agreement with the predicted distribution assuming that the maleimide content of ...
The ultrafast ( ~ 1000 reactions/day) and accurate (median error < ±1%) analysis of enantiomeric excess are achieved through the ion mobility-mass spectrometry combines with the diastereoisomerization strategy. A workflow for accelerated asymmetric reaction screening is established and verified...

The molar mass of a compound defines the mass of 1 mole of that particular substance and number of grams per mole of a compound. Molar mass can be calculated if the number of atoms and the atomic weight of the element is known.
To unearthA. muciniphila-derived bioactive factors, we first performed proteomic profiling of the secretome ofA. muciniphilacultivated under basal medium using nanoflow liquid chromatography-tandem mass spectrometry (nLC-MS/MS). A total of 2216 unique peptides corresponding to 325 proteins were ident...
The coefficient 𝐾ℎKh and 𝑘𝑟,𝑖kr,i in Equation (6) are absolute permeability and relative permeability, respectively. The mathematical formula describing the absolute permeability of hydrate deposits is generally related to the hydrate saturation. In this paper, the mathematical model propo...
