Uranus is much larger than Earth, with a surface area of 8.10 × 1015m2 with an atmosphere of low-density gases: 82.5% H2, 15.2%

Answer:

mass of Uranus: 9.31x10^22 kg

Explanation:

As I stated in the comments, the question in this problem is to calculate the mass of Uranus, given it's conditions.

Now, we have the data of the atmosphere gases, but for calculations, this data is irrelevant.

To calculate the mass of Uranus, we can use the second law of Newton which is:

F = m * a (1)

In this case, the only Force exerting here would be the weight so:

F = m * g (2)

And the force of Uranus, can also be expressed in terms of pressure and Area so:

F = P * S (3)

Now, if we replace (3) in (2) we have:

P * S = m * g

Solving for m:

m = P * S / g (4)

We have all the data, therefore, let's replace it in the above expression to calculate the mass of Uranus:

m = 1x10^8 * 8.1x10^15 / 8.7

m = 9.31x10^22 kg

This is the mass of Uranus

Fill in the missing piece of the table

Answer: The final volume $V_2$ is 263.09 ml

Explanation:

To calculate the final volume of the system, we use the equation given by Charles' Law. This law states that volume of the gas is directly proportional to the temperature of the gas at constant pressure.

Mathematically,

$\frac{V_1}{T_1}=\frac{V_2}{T_2}$

where,

$V_1\text{ and }T_1$ are the initial volume and temperature of the gas.

$V_2\text{ and }T_2$ are the final volume and temperature of the gas.

We are given:

$V_1=156ml\\T_1=215^oC=(215+273)K=488K\\V_2=?\\T_2=550^0C=(550+273)K=823K$

Putting values in above equation, we get:

$\frac{156}{488}=\frac{V_2}{823}\\\\V_2=263.09ml$

Thus final volume $V_2$ is 263.09 ml

What makes gabbro a rock and not a mineral

lozanna [386]

Gabbro is usually made up of such as pyroxene, plagioclase, amphibole and olivine which makes it an intrusive igneous rock. It is not considered as a mineral since it is composed of an aggregate of minerals or non-minerals and does not have one specific chemical composition.
