Some problems I just don't get.
What mass of C6H13BR will be produced by a reaction giving 65% yield if 12.5mL of liquid C6H12 (density = 0.673g/mL) is treated with 2.70L HBr (g) at STP?
C6H12 + HBr ----> C6H13Br
I don't understand what it means by density. Should I just work the problem by finiding the limiting reactant and caculate the theoretical yield and multiply it by a percentage?
