Question 3 (2 points) George wants to make a 0.1M solution of LiCI. He carefully measures 0.42g of lithium chloride into a flask and adds 100mL of water. He stirs the solution until all of the crystals are dissolved.What is the result? a George's calculation included mL instead of L. His solution has a molarity of 0.001moles/L b George should not have stirred the solution. His solution's molarity would have been correct otherwise. c. George did not calculate the molar mass of LiCl correctly. His solution has a molarity of 2moles/L. George did not use the correct amount of water. His solution has a molarity of 10moles/L. George used grams instead of moles in his calculation. His solution has a molarity of 70moles/L f George correctly made the solution

To determine the molarity of George's solution, we need to calculate the number of moles of lithium chloride (LiCl) and then divide it by the volume of the solution in liters.<br /><br />Given information:<br />- George wants to make a 0.1M solution of LiCl.<br />- He measured 0.42g of LiCl and added 100mL of water.<br /><br />Step 1: Calculate the molar mass of LiCl.<br />Molar mass of LiCl = Molar mass of Li + Molar mass of Cl<br />Molar mass of Li = 6.94 g/mol<br />Molar mass of Cl = 35.45 g/mol<br />Molar mass of LiCl = 6.94 g/mol + 35.45 g/mol = 42.39 g/mol<br /><br />Step 2: Calculate the number of moles of LiCl.<br />Number of moles of LiCl = Mass of LiCl / Molar mass of LiCl<br />Number of moles of LiCl = 0.42 g / 42.39 g/mol = 0.0099 moles<br /><br />Step 3: Calculate the molarity of the solution.<br />Molarity = Number of moles of solute / Volume of solution in liters<br />Molarity = 0.0099 moles / 0.1 L = 0.099 M<br /><br />Therefore, the correct answer is:<br />a) George's calculation included mL instead of L. His solution has a molarity of 0.099 moles/L.
