The density of metal block in grams per cubic centimeter is 10.70 g/cm³.
Given,
Mass of metal block = 5.16 lb
1 lb = 453.592 g
5.26 lb = 2340.536 g
The volume of metal block = 14 in 3
1 in = 2.5 cm
1 in 3 = 15.625 cm³
14 in 3 = 218.75 cm³
Density is defined as the mass per unit volume of a substance. Or, it is the ratio of mass to the volume of the substance.
As we know,
Density = mass/volume
Or, density = 2340.536 / 218.75
Or, density = 10.70 g/cm³
Therefore, the density of the metal block is 10.70 g/cm³.

Answer:
Vf = 1.22 mL
Explanation:
If we assume that the pressure is constant and the number of moles does not change, we can say that the volume of the gas is modified in a directly ratio, to the Absolute Temperature.
Let's convert the values:
91°C + 273 = 364K
0.9°C + 273 = 273.9K
Volume decreases if the temperature is decreases
Volume increases if the T° increases
V₁ / T₁ = V₂ / T₂ → 1.63mL /364K = V₂ / 273.9K
V₂ = (1.63mL /364K) . 273.9K → 1.22 mL
Answer:
using this for points, did you get the answer because I can try and help?
Explanation:
If the cube is 3 cm on each side, then it has a volume of 27 cm^3 (3 x 3 x 3). Density is mass divided by volume, so its density is 72.9/27 = 2.7 g/cm^3.
<span>Going by the density, the cube is made of Aluminium - density is a fairly unique quantity</span>
