Calculate the number of liters in 3.25 g of ammonia
il63 [147K]

 The liters in   3.25 g   of  ammonia  4.28 L


  <u><em>calculation</em></u>

 Step 1: find moles of ammonia

 moles = mass÷ molar  mass

 From  periodic    table  the molar mass  of ammonia (NH₃)  =  14 +(1×3 ) = 17  g/mol

3.25 g÷ 17 g/mol = 0.191   moles

Step 2: find the number of liters of ammonia

 that is at STP  1  moles = 22.4 L

                        0.191 moles = ? L

<em>by cross  multiplication</em>

 ={( 0.191   moles  ×22.4 L) / 1 mole}  = 4.28 L
