An aluminum block has a mass of 82.0 g and a volume of 12.8 cm3. what is the block's density to the nearest g/cm3?

aksik [14]

Density is mass over volume. If you put it into a formula it would look like this:

$D = \frac{m}{v}$

Based on the problem given, you can see that the mass of the aluminum block is 82.0 g and the volume is 12.8 cm3. Just put that into your equation and solve for it:

$D = \frac{m}{V}= \frac{82.0g}{12.8cm^{3} } = 6.4g/ cm^{3}$

The answer is then letter C.

How do you find the pressure in a container if you don't have the temperature?

BARSIC [14]

It depends on the process.
Like for example if the process is isothermal(temperature is constant), you can use,
PV = constant or P1V1 = P2V2 where P1V1 are initial conditions and P2V2 are final.

For adiabatic process,

PV^gamma = constant or P1V1 ^gamma = P2V2 ^gamma.

where gamma = Cp
------
Cv
Cp = specific heat at constant pressure and Cv = specific at constant volume.

Value of Gamma will be given in question.
Hope this helps!

The main group elements exclude which parts of the periodic table?*

Elden [556K]

Answer:

Transition metals and lanthanide metals

Explanation:

Alkali metals, alkaline earth metals, halogens, and noble gases are all part of the main group elements.

Periods and families simply refer to the rows and columns of the periodic table. They don't specify the type of element.

If the mass is 100g and the density is 0.8g/ml what is the volume

borishaifa [10]

volume is mass divide by density
100/0.8= 125mL
