Question

Find the molarity of the following solutions: Molarity - mole/Liters 1 liter = 1000 ml pter 1) 2.5 moles of NaCl is dissolved to make 0.050 liters of solution. 2) 3.0 moles of AgCl is dissolved in enough water to make a 2.0 liter solution 3) 4.2 moles of lithium fluoride are dissolved in 2 liters of solution. 4) 18 grams of hydrochloric acid, HCl is dissolved to make 1 liter of solution. Stoichiometry 1. 2Na+2H,0 ® 2NaOH+H, a). How many moles of sodium are required to produce 5.0 moles of NaOH, sodium hydroxide? b). How many moles of H, are produced in the reaction with 5.0 grams of water? 2. Sn + 2HF® SnF,+H, a). How many grams of SnF, are produced from the reaction of 30.0 g of HF? b) How many moles of HF will be needed to react with 10 moles of Sn?!

Answer 1

0.0 SOL Molarity modules are prob = som ® Molarity a mothers - 3501 -[1.5M 3 Molasity - males 2 mol = 2.1M] u moles of HCl = molens mass = the Salmo) = 0.50 moll Now, molaritys et boico me) = 0.50 M moled . SOM Now, 0.5 iters IL
