What is the density of a piece of wood that has a mass of 25.0 grams and a volume of 5.0 cm 3 ?
Georgia [21]

Answer:

5.0g/cm^3

Explanation:

Since we have the mass of the wood (25.0g) and the volume of the wood (5.0cm^3), can use the formula for density to answer this question.

Density=mass/density

Density=25.0g/5.0cm^3

Density=5.0g/cm^3

Therefore, the density of the piece of wood is 5.0g/cm^3.

I hope this helps!

liubo4ka [24]

Answer : The mathematical equation used when solving calorimetry problems is:

q=m\times c\times \Delta T}

Explanation :

Calorimetry : It is determining the changes in the energy of a system by measuring the heat transferred with surroundings.

Formula used :

q=m\times c\times \Delta T}

where,

c = specific heat capacity  of calorimeter

m = mass of a substance

q = heat required

\Delta T = change in temperature of substance
