How many grams of NaCl must react to produce 1.00 g Cl2?
Write the equation and balance it.
Convert 1.00 g Cl2 to moles. moles = grams/molar mass.
Using the coefficients in the balanced equation, convert moles Cl2 to moles Nacl.
Now convert moles NaCl to grams. g = moles x molar mass.

Well you just have to tune your flux capacitor to the desired speed and then you should be able to fly in space with no problem. Any more science questions just ask me :[)
