Expert Answer 1)ZnSO4.7H2O This means there are 1mol ZnSO4 and 7mol H2O The molar ratio of unhydrous salt (ZnSO4) to water is 1:7 2) percentage of water in the compound= (massof wa view the full answer Previous question Next question Get more help from Chegg The percentage by mass of water of crystallization in hydrated MgSO4.7H2O is approximate? The percentage of water of crystallization in ZnSO4.7H2O is [Zn = 65, S = 32, O = 1, H = 1] Correct Answer: Option B Explanation No official explanation is available for this question at this time. first step would be to calculate the molecular weight wt: ZnSO4 = 161.4g wt: 7H2O = 126 g total = 287.4g therefore the percentage of water would be wt of 7H2O divided by total weight times 100 126/287.4*100 = 43.8% same applies for the MgSO4.5H2O mass of Zn= 65, S=32, 0=16 and H= 1) Examples of molar mass computations: NaCl, Ca(OH)2, K4[Fe(CN)6], CuSO4*5H2O, water, nitric acid, potassium permanganate, ethanol, fructose. 7H2O] is approximately equal to (at. Molar mass of ZnSO4*7H2O is 287.5496 g/mol Convert between ZnSO4*7H2O weight and moles. Question: A Student Worked With A Sample Of ZnSO4*7H2O. 7h2o = 24+32+16×4+7×(2+16) = 24 +32+64+126 =246 246g of Epsom salt contains 126g of water.•. What Is The Molar Ratio Of Anhydrous Salt To Water? A). Examples of molar mass computations: NaCl, Ca(OH)2, K4[Fe(CN)6], CuSO4*5H2O, water, nitric acid, potassium permanganate, ethanol, fructose. The precipitate was filtered and dried, then ignited to produce 0.158 g of Zn2P2O7 (molar mass = 304.76 g/mol). 7H2O] is approximately equal to (at. You can change your choices at any time by visiting Your Privacy Controls. Side effects of excess supplementation may include abdominal pain, vomiting, headache, and tiredness.. Convert grams ZnSO4.7H2O to moles or moles ZnSO4.7H2O to grams. Yes! (As a matter of interest..If you take the mol.mass of the ZnSO4∙7H2O and then divide the mol.mass of the 7H2O by the total mol. ZnSO4.7H2O loses crystal water at 280 ̊C: • ZnSO4.7H2O = ZnSO4 + 7H2O (g) ZnSO4 Decomposes at 500 ̊C • ZnSO4 = ZnO + SO3 (g) ZnSO4.7H2O Usage: used in agriculture as animal feed additives, fertilizer and … Find out more about how we use your information in our Privacy Policy and Cookie Policy. The solution was neutralized with ammonia and subsequently warmed in a water bath. this question is asking what percentage of the total weihgt is water? Addition of (NH4)3PO4 to the solution resulted in the precipitation of ZnNH4PO4 . Examples of molar mass computations: NaCl, Ca(OH)2, K4[Fe(CN)6], CuSO4*5H2O, water, nitric acid, potassium permanganate, ethanol, fructose. Molar mass of ZnSO4*7H2O is 287.5496 g/mol Convert between ZnSO4*7H2O weight and moles. It will be deleted. ZnSO4∙7H2O. Its density is 3.31 g/cm 3, deliquescent in air.It disolves well in water. Moles = mass /moalr mass ie 60/287 = 0.21 moles 3) Since, in one mole of ZnSO4.7H2O there are 7 moles of water. 100g will contain 126×100÷246 = 12600÷246 = 51.21g of H2O Zincsulfateheptahydrate. AIPMT 1995: The percentage weight of Zn in white vitriol [ZnSO4 . 7446-20-0. Zinc Sulfate Heptahydrate ZnSO4.7H2O Molar Mass. b. Molar mass of ZnSO4.7H2O = 287.54956 g/mol. ... (CN)6], CuSO4*5H2O, water, nitric acid, potassium permanganate ... Hill formula, elemental composition, mass percent composition, atomic percent compositions and allows to convert from weight to number of moles and vice versa. Molar mass of ZnSO4.7H2O = 287.54956 g/mol. What isthe percent by mass of water in iron (II) sulfate heptahydrate, FeSO4 • 7H2O (or what percent of the molar mass of FeSO4 •7H2O is due to the waters of crystallization)? Yahoo is part of Verizon Media. ZINC SULFATE HEPTAHYDRATE. settings.no_comment_msg : 'There are no comments' }}. C) Calculate the percent of water … Calculate the percent by mass of water in magnesium sulfate heptahydrdrate (MgSO4-7H2O) Chemistry A hydrated MgSO4 salt, weighing 3.211g, is heated in a crucible until reaching a constant weight. 7446-20-0. Simply adding all the atomic masses of the elements, will give the Molecular mass of the hydrate. A) How many atoms of each kind are present?
