Chemistry Homework-- Stoichiometry: Volume and Particle Calculations
This is only to check my work, and I may be updating this post with more problems. There are ten questions total, and this is NOT graded. Therefore, the help I receive goes toward my understanding, not my score.
What VOLUME of oxygen is produced from the decomposition of 5.67 x 10^24 molecules of water?
Balanced equation:
2H2O >decomposes to> 2H2 + O2
6.02 x 10^23 molecules : 22.4L @STP for any gas
Mol-Mol ratio = 1 mol O2/ 2 mol H2O
Trying to go along with dimensional analysis format.
(5.67 x 10^24)/(6.02 x 10^23) x 1 mol O2/ 2 mol H2O x 22.4L = 105.488L
Is the mol-mol ratio necessary? Without it, the answer comes out to 210.977L (rounded).
