How to convert molecular weight from g/mol to lb/mol - Socratic
Mar 3, 2018 · Why would you want to do so? Well, there are 454*g*lb^-1..and so were we to convert the atomic mass of say ""^12C...we would take the quotient...
Conversion of a value between g/gmol and lb/lbmol
140g/g-mol = 140lb/lb-mol. that explanation is confusing to people the simplest way i have seen it explained is that 453.592gmol = 1 lbm-mol. so if you are given the weight of a substance say you have 1000lbm of hydrogen and you want to know the amount of moles. simply do 1000lbm * lbmol/2lbm = (500lbmol)*453.592gmol/1lbm-mol = 226,796 gmol.
mole - amu and g/mol relation - Chemistry Stack Exchange
Thus we have the important relationship: Da/ent = g/mol = kg/kmol, exactly. In other words, at the atomic level, the appropriate unit for amount-specific mass ("molar" mass) is dalton per entity--and, because of the mole definition as an Avogadro number of entities, dalton per entity is exactly equal to the macroscopic units gram per mole or ...

Nov 15, 2023 · $\begingroup$ Thank you. This is for HbA1c (glycated hemoglobin). I am not sure the molecular formula, but I have been told this: "Looking back to the definition of the measurand reported by the IFCC Working group on the standardization of HbA1c (i.e. HbA1c - N-(1-deoxyfructosyl)-haemoglobin-ß-chain) and considering that HbA is composed by two alpha …
Determining Formula - Chemistry - Socratic
The molecular mass of the compound is found to be 402 g/mol. What is the compound's chemical formula? The analysis of an organic compound showed that it contains 0.175 mol C, 0.140 mol H, and 0.035 mol N.
What is the molar mass of (NH4)2Cr207 (Ammonium dichromate)?
Dec 2, 2015 · The molar mass of ammonium dichromate is "252.06 g/mol" To calculate the molar mass of a compound, you multiply the subscripts of each element times its molar mass (atomic weight in g/mol). "(NH"_4)_2"Cr"_2"O"_7" When there is no written subscript, it is understood to be 1. Also, when elements are enclosed in parentheses, the subscripts on the inside are …
How to convert g/L to mol/L - Chemistry Stack Exchange
May 6, 2015 · I know I should divide $\pu{g L-1}$ by the molar mass of the substance, but I don't seem to find the specific answer on Google.
How many grams of iron are in 21.6 g of iron(III) oxide?
Aug 19, 2016 · Approx. 15*g of metal. "Moles of iron oxide, " Fe_2O_3 = (21.6*g)/(159.69*g*mol) = 0.135*mol with respect to the oxide. But by the composition of the oxide, there are thus 2xx0.135*molxx55.8*g*mol^-1 "iron metal" = ??g. An extraordinary percentage of our budgets goes into rust prevention; "iron(III) oxide" is only part of the redox chemistry. Once you put up …
