View Answer Q: Data Analysis: (1) Determine The Theoretical Yield Of The Alum By Calculating The Molar Mass Of The Potassium Aluminum Sulfate …Examples of molecular weight computations: C[14]O[16]2, S[34]O[16]2. Definitions of molecular mass, molecular weight, molar mass and molar weight. Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)Using 0.90 g of KAl(SO4)2 and 1.10 g of H2O, calculate the ratio of moles of water to moles of anhydrous KAl(SO4)2. Using 0.90 g of KAl(SO4)2 and 1.10 g of H2O, calculate the ratio of moles of water to moles of anhydrous KAl(SO4)2. Show step by step solution. Suppose you have 0.90 g of K A l ( S O 4 ) 2 and 1.10 g of H 2 O .The formula for alum is KAl(SO4)2 x 12 H2O. All of the atoms in this formula contribute to the molar mass. When you add up all the masses in the formula, the molar mass is 474.39 grams/mole. The molar mass of aluminum is 26.98. If you started this experiment with 1.063 grams of aluminum foil, what is the theoretical yield of Alum?. The chemical formula for hydrated potassium aluminuQuestion: 12 Calculate the mass of water Take the mass of the hydrate and subtract the mass of the anhydrate to get the mass of water. 17.70 g Na 2 CO 3 nH 2 O - 15.10 g Na 2 CO 3 = 2.60 g H 2 O. Divide the mass of water by the molar ...Massa Molar, Peso Molecular e Calculadora da Composição Elementar. Digite uma fórmula química para calcular a sua massa molar e composição de elementos: Massa molar of KAl (SO4)2 is 258.2050 g/mol. Ei! Examples of molecular weight computations: C[14]O[16]2, S[34] Write the empirical formula for the hydrated KAl (SO 4) 2, based on your experimental results and answer to Question 2. Hint: if the ratio of moles of H2O to moles of anhydrous KAl (SO4)2 was 4, then the empirical formula would be: KAl (SO4)2• 4 H2O. Describe any visual differences between the hydrated sample and the dried, anhydrous form.Examples of molecular weight computations: C[14]O[16]2, S[34]O[16]2.
