First calculate the molar mass of the anhydrous compound using … Mass required = volume (L) * molar mass * molarity . HPV. You find the atomic mass of the elements and × it by the number so Na is in group one which has 23 ram (relative atomic mass) so you × it by 2 and so on and add the results at the end. Mass = 0.5* 158.11 * 0.04 . The density of sodium thiosulfate corresponds to 1.667 grams per cubic centimetres. your summer job is at a photography lab, and you need to check the purity of an outdated supply. In its anhydrous form, sodium thiosulfate has a molar mass of 158.11 grams per mole. How many moles of Na2S2O3 are needed to react completely with 42.7 g of AgBr? The more commonly available pentahydrate from, Na 2 S 2 O 3.5H 2 O has a molar mass of 248.18 g/mol. Sodium Thiosulfate Na2S2O3 Molar Mass, Molecular Weight.
