A chunk of oak firewood has a mass of about 2.85 kg and has a volume of 4100 cm^3. Determine the density of oak in g/cm^3.
density=2850/4100 g/cm^3
To determine the density of oak, we can use the formula:
Density = Mass / Volume
The given mass of oak firewood is 2.85 kg, and the volume is 4100 cm^3. However, the density is commonly expressed in g/cm^3. Therefore, we need to convert the mass from kg to grams before calculating the density.
To convert kg to grams, we multiply the mass by 1000 since there are 1000 grams in 1 kilogram:
2.85 kg * 1000 g/kg = 2850 g
Now we can substitute the values into the formula:
Density = Mass / Volume
Density = 2850 g / 4100 cm^3
Calculating the density:
Density ≈ 0.695 g/cm^3
Therefore, the density of oak is approximately 0.695 g/cm^3.
