a)
Use the coefficients in the balanced equation to convert moles of one specie to moles of another.
2.74 mol Cl2 x (2 moles BrCl/1 mole Cl2) = 2.74 x (2/1) = ??
b)
Convert 239.7 g Cl2 to moles. moles = grams/molar mass.
Convert moles Cl2 to moles BrCl.
Finally, convert moles moles BrCl to grams. g = moles x molar mass.
c) Follow the same procedures remembering that there are 6.022 x 10^23 molecules in a mole.
