Charge of one electron is 1.6 × 10 −19 Coulomb. The mass of one mole of electrons is: 6.023 × 10 23 × 9.1 × 10 −31 Kg = 5.48 × 10 −7 Kg. The charge of one mole of electrons is. How do I calculate the rest mass of an electron in grams? AFAIK, there is no formula to calculate/compute the electron rest mass. Just look it up — enter the query 'electron rest mass in gram'! How many moles of electron weigh one kg: (mass of electron=9.109x10^-28 g)9.1101. 10^-31 kg contains 1 electron. Therefore, 1 kg will contain 1/(9.1101. 10 ^.
How do you calculate the mass of one mole of such hydrogen giving your answer to atoms four decimal places? (The Avogadro constant, L= #6.0225 xx 10^23 mol^-1#)?

#'Mass of 1 mole of hydrogen atoms'##=##'Mass of 1 hydrogen atom'xx'N'_A#, where #'N'_A=L=6.0225xx10^23*mol^-1#.
Explanation:
#'Mass of 1 hydrogen atom'##=##1.6727xx10^{-27}*'kg'# (from this site).
And thus, #'mass of 1 mole of hydrogen atoms'##=#
#1.6727xx10^(-27)*'kg'xx6.0225xx10^23*mol^-1xx10^(3)*'g'*kg^-1#
Consider a Multi-Family Sale. Garage sales advertised as 'community yard sales,' 'neighborhood. Call it a 'yard sale' or 'tag sale' if you prefer, but the meaning is clear: an 'everything must go' liquidation of the stuff you've accumulated over the years, advertised locally and held on or near your property. Throwing a garage sale is no easy feat.

#=1.007*'g'*'mol'^-1#
Apple music to deezer video. Clearly, you would not be expected to know these masses. You would be expected to be able to do such a calculation if provided with the masses of the nucleon, and with #'Avogadro's number'#.
