C + 2Cl2 = CCl4 1 atm and 0 deg C is STP so 276 L at STP = 276 L / 22.4 L/mole = 12.32 moles Cl2 From the balanced equation, you make 1/2 the moles of CCl4 that you have of Cl2 or 6.16 moles CCl4. To get the mass of CCl4, multiply by the molar mass of CCl4.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
