Announcements- There is a quiz tomorrow (if no snow day) ...but since there is one, the quiz will be probably on Friday.

Today In Class- We went in further in the unit, this time we learned about solving for Density.To figure out how to solve for the Density of X, you need to first figure out the "given" of the object. For example, on page 23,
#1 a) What mass of oxygen is required to produce 65g of CO2?

b) If the density of O2 is 0.00143 g/ml, what volume of oxygen is this?

When figuring out the density of a problem, you DO NOT do anything different all you do is add one more step into the equation and then solve.
another example is on page 24, #3
