Write down the consentration of 117g of NaCl in 2l solution |
|
Answer» The molar mass of NACL is 23+35.5=58.5 g/mol. The mass of NaCl is 117 GRAMS. The NUMBER of moles of NaCl is 117/58.5 = 2 molesMolarity of solution is the number of moles of NaCl present in 1 L of solution. Hence, the molarity of NaCl is 2 mol/1 liter = 2M |
