Answer:

Explanation:
The density formula is mass over volume.

Rearrange the formula for the mass, m. Multiply both sides of the formula by v.


Mass can be found by multiplying the density and volume. The density is 0.65 grams per milliliter and the volume is 45.0 cubic centimeters.
- A cubic centimeter is equal to a milliliter.
- Therefore, 45 cubic centimeters also equals 45 milliliters.

Substitute the values into the formula.

Multiply. Note the milliliters, or mL will cancel out.


The mass of the wood is 29.25 grams.
2H2O=2H2+O2
37.4g H2O(1 mol/18.02)=2.07547 mol H2O
PV=nRT
(1.30)(V)=(2.07547)(.0821)(297)
Vwater=38.92898L
38.92898L (1 mol O2/2 mol H2O)=19.46449L O2 gas
