Date ID: A ment or answers the question. 5. To prepare 0.250 L of 0.100 Maqucous NaCl (NaCl: 58.4 g/mol), onc may a. dissolve 0.100 g of NaCl n 250 ml. of water. b. dissolve 1.46 g of Naci in 250 mL of watcr. c. dissolve 0.100 g of Naci in enough water to make 0.250 kg of solution. d dissolve 1.46 g of NaCI in enough water to make 0.250 L of solution, e. dissolve 0.100 g NaCl in 0.250 kg of water. 6. If 25.00 mL of 6.00 M HCI is transtorred by pipet into a volumetric flask and diluted to 5.00 L what is the molarity of the diluted HCl? 0.0300 M 055 M 0.75 M d 43.0 M 20 x 7. What volume of 2.0 M NaCI is required to prepare 50 ml of 0.10 MNaCI? 7.5 mL 75 mL 3.0 L 8. What mass of Ca(NO)a (137 6 gmol) is present in a 291 g /.23 m ie a d is 4% HNO by mass and has a density
