The density of the mineral sample is 1.67 g/cm3. This is calculated by dividing the mass (20g) by the volume (12cm3).
The density of the object is calculated by dividing the mass (108g) by the volume (12cm3). Therefore, the density is 9g/cm3.
The density of the object is 3 g/cm3. This is calculated by dividing the mass (36 g) by the volume (12 cm3).
r = 0.977 cm
12cm3
2x3x2=12cm3
The formula you need is D=m/v, where D is the density, m the mass and v the volume. 1ml = 1cm3 so 12ml = 12cm3 D (in this case) = 4.05/12 = 0.3375 g/cm3
The answer is 2 g/cm3How to figure out: When figuring out these things, the best hint is looking at what kind of answer you expect. In this case you are looking for density: weight (g) per volume (cm3). This is denoted as g/cm3. In words that is "g divided by cm3". So you divide 24 g by 12 cm3.24 g / 12 cm3 = 2 g/cm3.
A rectangular prism whose dimensions are 2.0 cm and 3.0 cm and 2.0 cm has a volume of 12cm3
A rectangular prism whose dimensions are 2.0 cm x 3.0 cm x 2.0cm has a volume of 12cm3
Vol = 3 cm * 2 cm * 2 cm = 12cm3 = 12 millilitres.
An impossibility. An area is a 2-dimensional measure whereas the figure in the question is a 3-dimensional measure of volume. The two are measures of different things and there is no relationship between them.
Oh, dude, you're hitting me with some math here! So, to find the volume, you just divide the mass by the density. So, 15.1g divided by 3.52g cm3 equals about 4.29 cm3. Voilà, you've got your diamond volume! Like, who needs a ruler when you've got math, right?
