A container has 150.0 mL of an aqueous solution containing NH4+ ions. How many grams of NH4+ ions are in the solution if the molarity is 0.580 M?

Solutions

Expert Solution

molarity of solution = 0.58M

volume of solution    = 150ml     = 0.15L

no of moles of NH4^+     = molarity * volume in L

                                      = 0.58*0.15   = 0.087 moles

mass of NH4^+     = no of moles * gram molar mass

                             = 0.087*18   = 1.566g of NH4^+ ions >>>>answer
