Calculate the mass of potassium chlorate needed to prepare 5.00L of oxygen gas
« on: November 19, 2006, 06:31:10 PM »
If you have seen my other post, you will know that I have been out of the chemistry thing for a number of years.....so, I am a bit rusty, and well, stuck at some times....Please help me figure out how to do this:
Calculate the mass of potassium chlorate needed to prepare 5.00L of oxygen gas at 24 ºC and 0.950 atmusing the gas constant R=0.0821 LxatmxmolxK
The equationis:KClO3 -->KCl + 3/2 O2

I tried a bunch of different things but can't conclude it! *delete me*
thanks!

Most Common Suggestions I Make on the Forums.
1. Start by writing a balanced chemical equation.
2. Don't confuse thermodynamic stability with chemical reactivity.
3. Forum Supports LaTex
