A 40.8 mol sample of methane gas, CH4(g), is placed in a1020 L container at 298 K.
What is the pressure, in atm, of the methane gas?
Express the answer using 3 significant figures.
atm

Answers

Answer:

P = 0.979 atm

Explanation:

Given data:

Number of moles of methane = 40.8 mol

Volume of container = 1020 L

Temperature = 298 K

Pressure of gas =?

Solution:

According to ideal gas equation,

PV = nRT

P = pressure

V = volume

n = number of moles

R = general gas constant

T = temperature

Now we will put the values,

P = nRT/V

P = 40.8 mol × 0.0821 atm.L/mol.K × 298 K / 1020 L

P = 998.2 atm /1020

P = 0.979 atm

Why is there a greater variety of compounds than of elements and atoms?

Answers

Despite the fact that there are over 100 elements .The elements containing  electron, proton neutron as well, could  be combined to create new things, making the possibilities unlimited.

What is elements?

A pure substance made up entirely of atoms with the same number of protons in each nucleus is known as an element.

What is electrons?

An electron is just a subatomic particle with a negative charge.  The energy levels of electrons in atoms are represented by spherical shells of different kinds of diameters.

Which statement describes the chemical property of oxygen

Answers

The chemical property of oxygen is best described by oxygen's ability to combine with a metal to produce a compound. Oxygen is a highly paramagnetic and highly reactive element which supports combustion.

One balloon was only partly filled when put on the plane. During the flight, the balloon volumeincreased from 7 L at 1.0 atm to 9 L. What was the cabin pressure on the airplane during the flight?
(Assume the balloon stretched very easily and the temperature was constant.)

Answers

Answer:

P₂ = 0.8 atm

Explanation:

Given data:

Initial pressure = 1 atm

Initial volume = 7 L

Final volume = 9 L

Final pressure = ?

Solution:

P₁V₁ = P₂V₂

P₁ = Initial pressure

V₁ = Initial volume

P₂ = Final pressure

V₂ = Final volume

Now we will put the vales in formula.

P₁V₁ = P₂V₂

P₂ = P₁V₁ /V₂

P₂ = 1 atm × 7 L / 9 L

P₂ = 7 atm. L / 9 L

P₂ = 0.8 atm
