How many sig figs?
posted by Hannah .
For this question: what is the boiling point of 0.39 mol ethylene glycol and 0.13 mol KBr in 155 g H2O?
I got 102.1470968 and I tried it with 2 and with 3 sig figs but it's both wrong. I know that's the correct answer but I don't know how many sig figs I'm suppose to use

two sig figures .39 and .13
