Homework Help: Chem help?

Posted by sool on Thursday, February 7, 2008 at 11:10pm.

In an experiment 5.57 +/- 0.02 grams of water chemically decomposes into the products hydrogen gas and oxygen gas. The measured mass of oxygen gas produced in the reaction is 4.9320 +/- 0.0001 grams. The hydrogen gas occupies a volume of 6902 mL. Report the density of the hydrogen gas produced to the correct number of significant digits (Do not perform any calculation involving the estimates of uncertainties in the measurements.)

My answer is 9.24 *10^-5....Is it the right num of sig figs?
