More Stoichiometry

Remember last class when Mr. Doktor introduced us to the wonderful work of stoichiometry?(If you don't we wrote a blog about that one too! haha) Well today we learnt even more!! In adition to moles to mass conversions, we learnt how to solve mass to mole conversions. We also learnt how to solve problems involving volume at STP(22.4L). To help you remember info about volume at STP the chart below could be very handy. You can use this chart to help you by seeing which order to convert your elements and by how much.

Here's a quick example..

What mass of water vapour is produced when 3.5L of Hydrogen is burnt(with oxygen) at STP?

And here's a little video of a guy with a cool accent to try to explain it for ya!!
