Chapter 1, Problem 2P

A student extracted starch from a 5.0g sample of banana. The total volume of banana extract she collected was 22.5ml . The weight of the filter paper alone was 0.172g. The wet weight of the filter paper with starch was 1.158g. The dry weight of the filter paper with starch was 0.894g.   How much absorption you would expect to see for cuvette that contains 0.75mg of glucose? A) 0.18 B) Cant answer that question without knowing how much of the banana extract was used C) 0.468 D) 0.367

umerical 1.2 2.5 moles Step 4 Calcula number of moles 11 M 8,00 g 2 g.mol = 4 moles Step 5 Write down the 2 moles H, reacts with 1 mole O moles in the reaction Step 6 Determine the mass of the product(s) Step 7 Conclusion 4 moles H, reacts with 2 moles O, Mass of O, consumed: m=nxM = 2,00 mol x 32 g.mol-1 = 64 g 64 g of oxygen is consumed. therefore: Theor The calcula theoretical we find th escape or can calcul Percen 4 3 1 Activity 1 Perform stoichiometric calculations In the following chemical reaction: 2H2(g) + O2(g) → 2H₂O(g) 1.1 How many moles of H₂O will be produced from 6 moles of O₂? 1.2 How many moles of H₂ will react with 40 g of O₂? 1.3 How many grams of H₂O will be produced by 18 g of H₂? 2 Zinc metal is used to displace silver from a silver nitrate solution in accordance with the following equation: Zn(s) + 2AgNO3(aq) → Zn(NO₂)2(aq) + 2Ag(s) What mass of zinc should be used to displace 60 g of silver from excess silver nitrate solution? -> 80 g of magnesium react with…
