A 1.00-mole sample of dry ice (solid CO₂) is placed in a flexible, sealed container and allowed to sublime. After complete sublimation, what will be the
container volume, in liters, at 26°C and 0.983 atm pressure?

Respuesta :

Container volume, 26°C, and 0.983 atm pressure is =24.9 liters.

What is a Moles?

  • A mole is defined as the quantity of a material that includes precisely 6.02214076 X 1023 of the substance's elementary entities.
  • A substance is said to have a mole with a mass equal to 12.000 g of 12C and the same number of basic units as atoms.
  • The mole can be used to calculate the quantities involved in chemical processes and identify the simplest formula of a compound. The molarity notion, which is related, helps discuss reactions in solutions. The number of moles of a solute in a liter of solution is known as molarity (M).
  • Quantities that cannot be quantified using units like grams or milligrams are referred to as moles. A mole thus counts the quantity of atoms, ions, or molecules.  

Container volume, in liters, at 26°C and 0.983 atm pressure:

Given=1.00

V=?

PV=nRT

T=26°C+273.15

=299.15K

R=0.08201Lamt/k

P=0.983atm

V=nRT/p

[tex]V=\frac{1.00 mole(0.08201Lamt/k)299.15K}{0.983atm}[/tex]

V=24.9 liters

Container volume, 26°C, and 0.983 atm pressure is =24.9 liters.

The Volume in the container is 25L .

What is Ideal Gas?

Ideal gas is hypothetical gas whose molecules occupy negligible space and have no interaction, and which consequently obeys the gas laws exactly.

We have given

Pressure=0.983atm

moles=16

Temperature= 26°C

T →273+26=299K

Volume = ?

PV = nRT

V= 1×0.0821×299/0.983

By solving this equation we get

V= 24.9L≈25L
