How can you describe ideal gas particles? Check all that apply.
nevsk [136]

The description of an ideal gas is as follows:

  1. They have a small mass
  2. They have a small volume
  3. They have no intermolecular forces

<h3>WHAT IS AN IDEAL GAS?</h3>

An ideal gas is a theoretical gas composed of many randomly moving particles that do not engage in any inter-particle interactions.

An ideal gas obeys all the gas laws and possess the following characteristics:

  1. They have a small mass
  2. They have a small volume
  3. They have no intermolecular forces

Part 1. Determine the molar mass of a 0.622-gram sample of gas having a volume of 2.4 L at 287 K and 0.850 atm. Show your work.
zaharov [31]

If a sample of gas is a 0.622-gram, volume of 2.4 L at 287 K and 0.850 atm. Then the molar mass of the gas is 7.18 g/mol

<h3>What is an ideal gas equation?</h3>

The ideal gas law (PV = nRT) relates to the macroscopic properties of ideal gases.

An ideal gas is a gas in which the particles (a) do not attract or repel one another and (b) take up no space (have no volume).

Given :

  • V = 2.4 L = 0.0024
  • P = 86126.25 Pa
  • T =  287 K
  • m = 0.622
  • R = 8.314

The ideal gas equation is given below.

n = PV/RT

n = 86126.25 x 0.0024 / 8.314 x 287

n = 0.622 / molar mass (n = Avogardos number)

Molar mass =  7.18 g

Hence, the molar mass of a 0.622-gram sample of gas having a volume of 2.4 L at 287 K and 0.850 atm is 7.18 g

More about the ideal gas equation link is given below.

How much energy, in joules, is released when 17 kilograms of granite is cooled from 45 C to 21 C?
Lostsunrise [7]
Answer is: <span>D. 327,992.8 J.
</span>m(granite) = 17 kg = 17000g.
ΔT(granite) = 21°C - 45°C = -24°C (-24K).<span>
cp(granite</span>) = 0,804 J/g·°C, <span>specific heat capacity of granite.
Q = m(granite</span>) · ΔT(granite) · cp(granite).<span>
Q = 17000 g ·(-24</span>°C)<span>· 0,804 J/g·K.
Q = -327990 J.
</span>The granite lost 327990 joules of energy.<span>
Q - </span>amount of energy gained or lost.<span> 
</span>
