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- …

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 …

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 …

Mar 19, 2018 · 40 \ "g/mol". On the periodic table, it shows us that calcium has a mass of around 40 \ "amu". We now need to convert from "amu" to "g/mol". We know that the mass of one …

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.

Jun 25, 2015 · Here's how you'd go about solving these questions. Part A To get from grams of a substance to moles you need to use molar mass. Molar mass tells what the exact mass of 1 …

Dec 4, 2015 · Now it is a fact that while the empirical formula may NOT be the same as the molecular formula, the molecular formula is ALWAYS a multiple of the empirical formula. So, …

Jul 17, 2016 · Next, you have 3 hydrogen atoms, so you would multiply the atomic mass of H by 3 to obtain an atomic weight of 3.024 g/mol. Now you want to add the mass of each atom …

Dec 31, 2021 · As measurements get more accurate, the value will change a bit over time. The mass of a particle and the molar mass of the pure substance made of those particles is …

What this tells us is that the ratio of g/mol to amu/atom is exactly one - and we made sure it would work out that way by carefully choosing how we defined moles and amus. Since the masses of …
