Answer:

When the solar system settled into its current layout about 4.5 billion years ago, Earth formed when gravity pulled swirling gas and dust in to become the third planet from the Sun. Like its fellow terrestrial planets, Earth has a central core, a rocky mantle and a solid crust.

A sample of methane gas collected at a pressure of 0.884 atm and a temperature of 6.00 C is found to occupy a volume of 26.5 L.

Genrish500 [490]

Answer:

1.03mole

Explanation:

Given parameters:

Pressure = 0.884 atm

Temperature = 6°C = 273 + 6 = 279k

Volume = 26.5L

Unknown:

Number of moles = ?

Solution:

To solve this problem, we use the ideal gas equation:

PV = nRT

P is the pressure

V is the volume

n is the number of moles

R is the gas constant = 0.082atmdm³mol⁻¹K⁻¹

T is the temperature

n = $\frac{PV}{RT}$ = $\frac{0.884 x 26.5}{0.082 x 279}$ = 1.03mole
