Check whether the answer isreasonable.The volume of a soda can is 1/3 L. 0.1 moles of sucrose isneeded; the answer is reasonable.How to calculate grams of solute in a given volume of solutionA physiological saline solution is 0.154 M NaCl. How many grams of sodium chloride are in 500. mL ofthe solution?Solution:Write down the given values with theirunits and what they represent.In this problem, molarity is given for the solute NaCl andthe solvent water. The molar masses of Na and Cl can beobtained from the Periodic Table.M NaCl = 0..154 mol NaCl/L salineV saline = 500. mL1 mol Na = 22.99 g/mol1 mol Cl = 35.45g/molmolar mass NaCl = 58.44 g/molWrite down the unknown and its unit.The grams of NaCl in 500. mL of saline is unknown.g NaCl = ?Develop a strategy to solve the problem.The definition of molarity isA dimensional analysis problem is set up to give g NaCl in500. mL saline.
Round off the answer to the correctnumber of significant digits and give theappropriate units.The molarity and volume saline have 3 significant digitswhile the molar mass has 4. The mass is rounded off to 3significant digits. The answer ismass = 4.50 g NaClCheck whether the answer is reasonable.The volume of saline is 0.5 L. 0.075 moles of NaCl wouldbe present; the answer is reasonable.
