3. A solution of 20.91 % by weight H,SO, has a specific gravity of 1.150. What is the normality of this solution? Water is added to dilute this solution to a solution of 3.03% by weight H,SO, (SG= 1.020). What is the new normality of the resulting solution and how were they mixed? (Assume 100 ml of the original solution was used.)

please kindly answer number 3 asap.include the given and required in each letter. i really need this now. thank tou very much
Solve the following problems neatly and completely. Express all answers to the nearest fourth decimal place. No unit or wrong unit means wrong answer. 1. A solution is made by dissolving 0.100 mole of NaCl in 8.60 mole of water. a) What is the mole fraction of the solute? b) What is the mass percent of the solute? c) What is the molality of the solute? 2. An automobile antifreeze mixture is made by mixing equal volumes of ethylene glycol (SG= 1.114; MW = 62.07 g/mole) and water at 20°C. The density of the mixture is 1.070 g/mL. Express the concentration of ethylene glycol as a) Volume percent b) Mass percent c) Molarity d) Molality e) Mole fraction 3. A solution of 20.91 % by weight H,SO, has a specific gravity of 1.150. What is the normality of this solution? Water is added to dilute this solution to a solution of 3.03% by weight H,SO, (SG= 1.020). What is the new normality of the resulting solution and how were they mixed? (Assume 100 mL of the original solution was used.) 4. An aqueous solution of ferric hydroxide has a specific gravity of 1.25 and a weight fraction of solute equal to 0.10. Calculate: a) % solute by mole b) Molality of the solution c) Normality of the solution d) ppb of solute
