Aplanet has a surface temperature of 95.0 k and an atmospheric pressure of 1.60 atm. if 4.87 l of atmosphere has a mass of 28.6 g, what is the average molar mass of the atmosphere? use r=0.08206l atmmol k for the gas constant. your answer should include three significant figures.

M=28.88 gm/mol

Explanation:

Given that

T= 95 K

P= 1.6 atm

V= 4.87 L

m = 28.6 g

R=0.08206L atm .mol .K

We know that gas equation for ideal gas

P V = n R T

P=Pressure , V=Volume ,n=Moles,T= Temperature ,R=gas constant

Now by putting the values

P V = n R T

1.6 x 4.87  = n x 0.08206 x 95

n=0.99 moles

We know that number of moles given as

M=Molar mass

M=28.88 gm/mol

the journeys of marquette, joliet and la salle a) new france expand.

all three of these explorers explored the midwest and the area around the great lakes, which they subsequently claimed for france.

this was a big portion of territory and expanded new france which before then only consisted of quebec province in northeastern canada
