Homework Help: How many sig figs?

Posted by Rachel on Sunday, April 17, 2011 at 1:13pm.

An equilibrium mixture of the following reaction was found to have [H2] = 0.020 M and [I2] = 0.020 M at 340C. What is the concentration of HI?
H2(g) + I2(g)--> 2 HI(g)
Keq = 69 at 340C

I got .166 but it said check number of sig figs so im guessing its 2 sig figs but I want to make sure:)

Thanks
