2014-05-06 · What was the mass of the salt after it was dried by heating? (#m_2#)? #m_w# = mass of water. #m_w# = #m_1# - #m_2# convert this to moles of water by dividing by the molar mass of water which is 18.02 g/mol. Convert the mass of the anhydrous salt (#m_2#) by dividing it by the molar mass of the anhydrous salt. The moles of salt should be the

2015-10-29 · "58.44277 g/mol" Sodium chloride, also known as table salt, is an ionic compound composed of sodium cations, "Na"^(+), and chloride anions, "Cl"^(-) that has the formula unit "NaCl". The molar mass of an anionic compound tells you what the mass of one mole of formula units of that respective compound is. You know that sodium chloride's formula unit contains one sodium atom one chlorine atom Preparation of Mohr's salt: Mohr's salt is prepared by dissolving an equimolar mixture of hydrated ferrous sulfate and ammonium sulfate in water containing a little sulfuric acid, and then subjecting the resulting solution to crystallization.
