Apiece of wood that measures 3.0 cm by 6.0 cm has a mass of 80.0 grams. what is the density of the wood. would it float?

Density = 1.11 g/cm³, will not float on water

Explanation:

Assuming the other dimension missing is 4.0 cm

Then we can find the volume of the piece of wood.

Volume = Length × width × height

Volume = 6.0 cm × 3.0 cm × 4.0 cm

             = 72 cm³

We are required to find the density of the wood.

Density = mass ÷ Volume

Mass of the wood = 80.0 grams

Therefore;

Density = 80.0 g ÷ 72 cm³

            = 1.11 g/cm³

Hence, the density of the wood is 1.11 g/cm³

Water has a density of 1 g/cm³ and therefore the wood will not float since it is denser than water.

"standard molar enthalpy:

h2o ( liquid water ) : - 285.8 kj/mole

h2o ( water vapor ) : - 241.8 kj / mole.

δhrxn = - 241. 8 - ( - 285.8 )= -241.8 + 285.8 = 44.0

answer: 44.0 kj"
