Find the volume of 51.1 g of O2 at 24.1°C and 119.5 kPa. i really need help with this.
i have 5 questions after this if you could. ill give whatever awards I can

It has to be b i hope this

Is a logical series of steps

  the volume of  0.220 m k2s    solution  required  to  completely  react with 175 ml  of 0.115m co(no3)2  calculate the moles  of co(no3)2 =  molarity x volume/1000175 x0.115/1000= 0.02  moleswrite  the reacting  equationk2s(aq)  +  co(no3)2  = 2 kno3(aq)  + cos(s)by  use  of mole ratio between k2s to co(no3)2 which  is  1: 1 the moles of k2s is therefore = 175  x0.115/1000= 0.02  molesvolume = moles/molarity=0.02/0.22=0.09  ml  of k2s

It depends on how many moles there are, if you have about 4 moles you must divide that number by 2.5 and add 14 to it and you will get your answer.
