P=20707.7 atm

<h3>What is the molar form of the ideal gas law?</h3>

The ideal gas law is a straightforward formula that describes the relationship between an ideal gas's pressure P, volume V, and temperature T. Unless there is a strong reason to treat gases differently, we normally treat gases as ideal because of how straightforward this relationship is:-

PV=nRT

where ;

P= Pressure=?

V= Volume= 10.5 L

n= no.of mol.= 82.5 mol

R=Ideal gas constant= 8.314 joule / mol kelvin

T=Temperature= 317 K

using Given value:-

P= nRT/ V

P=(82.5 x 8.314 x 317) / 10.5

P=20707.7 atm

A 2.00 liter evacuated container has a mass of 1050.0 g. When the container is filled with an unknown gas at 800. mm Hg pressure
Andrei [34K]

Answer:

(A) 28

Explanation:

To solve this problem we use the <em>PV=nRT equation</em>, where:

  • P = 800 mmHg ⇒ 800/760 = 1.05 atm
  • V = 2.00 L
  • n = ?
  • R = 0.082 atm·L·mol⁻¹·K⁻¹
  • T = 25.0 °C ⇒ 25.0 + 273.16 = 298.16 K

We<u> input the data</u>:

  • 1.05 atm * 2.00 L = n * 0.082 atm·L·mol⁻¹·K⁻¹ * 298.16 K

And <u>solve for n</u>:

  • n = 0.086 mol

Now we calculate the gas' mass:

  • Gas Mass = (Mass of Container w/ Gas) - (Mass of Empty Container)
  • Gas Mass = 1052.4 g - 1050.0 g = 2.4 g

Finally we <u>calculate the unknown gas' molar mas</u>s, using<em> its mass and its number of moles</em>:

  • Molar Mass = mass / moles
  • Molar Mass = 2.4 g / 0.086 mol = 27.9 g/mol

So the answer is option (A).

The alveoli are surrounded by __________ carrying blood to and from the heart.
natka813 [3]
The alveoli are surrounded<span> by tiny blood vessels, called capillaries. The </span>alveoli<span> and capillaries both have very thin walls, which allow the oxygen to pass from the </span>alveoli<span>to the blood. The capillaries then connect to larger blood vessels, called veins, which bring the oxygenated blood from the lungs to the heart.</span>

How are isotopes of the same chemical element alike? How are they different?
Stella [2.4K]

<u>Answer:</u> The atomic mass of these species is different and atomic number remains same.

<u>Explanation:</u>

Isotopes are the chemical species of the same element having different number of neutrons.

  • Atomic number is equal to the number of protons or electrons present in that element.

Atomic Number = Number of electrons = Number of protons

  • Atomic mass is defined as the sum of number of protons and neutrons contained in an atom.

Atomic Mass = Number of protons + Number of neutrons

For isotopes, as the number of neutrons differ, the atomic mass also differs.

For Example: Carbon has 3 naturally occurring isotopes: _6^{12}\textrm{C},_6^{13}\textrm{C}\text{ and }_6^{14}\textrm{C}. The atomic number remains the same but atomic mass differs.

Hence, for isotopes, the atomic mass of these species is different and atomic number remains same.

Only 11% of all the energy used in the US comes from a renewable source. Why is this a<br> problem?
mr Goodwill [35]
Fossil fuels and unnatural energy sources still dominate in the US, this influences many problems including global warming, climate change, and pollution. Burning fossil fuels is also a problem to human health. And unnatural resources won’t be there forever whereas, renewable sources could last a long time.
