A balloon is filled to a volume of 5.0 102 mL at a temperature of 28.0°C. The balloon is then cooled at constant pressure to a temperature of 1.00 102 K. What is the final volume of the balloon?
the answer i got is v=166.66666667
My question is what is the correct sig. figures of that number.

Two significant digits (volume 5.0 tells you that)

so 166.66?

170 ml
