Answer:

1.8 moles

Explanation:

Number of moles = ?

Pressure = 15.4 atm

Volume = 2.92L

Temperature = 32°C = (32 + 273.15)K = 305.15K

From ideal gas equation,

PV = nRT

P = pressure of the ideal gas

V = volume in which the gas occupies

n = number of moles

R = ideal gas constant = 0.082J/mol.K

T = temperature of the gas

PV = nRT

n = PV / RT

n = (15.4 * 2.92) / (0.082 * 305.15)

n = (44.968 / 25.0223)

n = 1.797 moles = 1.8 moles

Number of moles of the gas is 1.8 moles

What does continental drift and sea floor spreading have in common
Llana [10]

In the early 1900s, a scientist named Alfred Wegener noticed how the continents seem to fit together and developed the Theory of Continental Drift. Continental drift is the theory that continents can drift apart from one other and have done so in the past. Wegner's theory also explained why fossils of the same plant and animal species are found on both sides of the Atlantic Ocean. In addition similar types of rock and evidence of the same ancient climatic conditions are found on several continents.

Wegner hypothesized that all the separate continents of today were once joined in a single landmass that he called Pangaea.
