oakwood has a mass of 2.85 kilograms and a volume of 4100 cubic centimeters. determine the density of oak in grams per cubic cen

bogdanovich [222]

Answer:

The density of oak is <u>0.695</u> grams per cubic centimeter.

Step-by-step explanation:

Given:

Oakwood has a mass of 2.85 kilograms and a volume of 4100 cubic centimeters.

Now, to find the density of oak in grams per cubic centimeter.

Mass (m) = 2.85 kilograms.

So, using conversion factor we convert into grams:

$2.85\times 1000=2850\ grams.$

Volume (v) = 4100 cubic centimeters.

Now, to get the density by using formula:

$Density=\frac{mass}{volume} \\Density=\frac{m}{v}$

$Density=\frac{2850}{4100}$

$Density=0.695\ grams\ per\ cubic\ centimeter.$

Therefore, the density of oak is 0.695 in grams per cubic centimeter.
