Question: Question 44 How many grams of KCl (molar mass = 74.55 g) will be produced fror reaction of 50.0 mL of 0.300 M KOH with excess HCI? KOH (aq) + HCl (aq) - KCl (aq) + H2O O 6.98 g O 1.12 g O 9.31 g O 4.958.Example: calculating molar mass. Let's calculate the molar mass of carbon dioxide (CO 2): Carbon (C) has an atomic mass of about 12.01 amu. Oxygen (O) has an atomic mass of about 16.00 amu. CO 2 has one carbon atom and two oxygen atoms. The molar mass of carbon dioxide is 12.01 + (2 × 16.00) = 44.01 g/mol. Lesson on computing molar massThe problem provides you with a #"24.7-g"# sample of potassium chloride, #"KCl"#, and a total volume of a solution of #"500. mL"#. In order to find the number of moles of potassium chloride, your solute, use the compound's molar mass, which as you know tells you the mass of one mole of potassium chlorideWhich of the following concentration values has the HIGHEST mass of KCl (molar mass: 74.55 g/mol) dissolved in water (molar mass: 18.02 g/mol)? Consider 100-gram solutions with a density of 1.00 g/mL. a. 0.050 molar KCl solution b. 0.50 molal KCl solution c. Solution with KCl mole fraction of 0.050 d. 5.0% by mass KCl solutionYou need to divide 10 g by the total mass and multiply by 100% to get your answer. For example, if you have 1 kg in total, then mass percentage concentration is 1 % because 10 g / 1000 g × 100% = 1%. The concentration calculator helps you to recompute concentration (molarity and percentage concentration)..
