Answer:

Total pressure = 6.95 atm

pN2)  4.34 atm

p(Ne) =0.44 atm

p(H2) =  2.18 atm

Explanation:

Step 1: Data given

The N2 sample = 7.0 liter at 3.50 atm

The Ne sample = 2.5 liter at 1.00 atm

The H2 sample = 5.0 L at 2.45 atm

Temperature = 25.0 °C

Concentration = 0.160 mol/L

Step 2: Calculate moles

p*V = n*R*T

n = (p*V)/(R*T)

⇒ n = the number of moles of gas

⇒ V = the volume of gas

⇒ p = the pressure of gas

⇒ R = the gas constant

⇒T = the temperature

n(N2) = (3.50*7.0)/(0.08206*298 K)

n(N2) = 1.00 moles

n(Ne) = (1.00*2.5)/(0.08206*298)

n(Ne) = 0.102 moles

n(H2) = (2.45 * 5.0) / (0.08206*298)

n(H2) = 0.501 moles

Step 3: Calculate mol fraction

Total moles = 1.00 + 0.102 + 0.501 = 1.603 moles

Step 4: Calculate mol fraction

Mol fraction = moles gas / total moles

Mol fraction N2 = 1.00 / 1.603 = 0.624

Mol fraction Ne = 0.102/1.603 = 0.0636

Mol fraction H2 = 0.501 / 1.603 = 0.313

Step 5: Calculate total pressure

Total pressure = 3.50 atm + 1.00 atm + 2.45 atm

Total pressure = 6.95 atm

Step 6: Calculate partial pressure

pN2) = 0.624 * 6.95 = 4.34 atm

p(Ne) = 0.0636 *6.95 =0.44 atm

p(H2) = 0.313 *6.95 = 2.18 atm

Mike, Jackie, Jeremy, and Niki were widely known to the be the fastest fifth graders at Robinson Elementary School. They wanted
riadik2000 [5.3K]

Jackie is the fastest student. (Option A)

Explanation:

  • From the table it was understood that their speeds are given in meter per second, that is how many meters they run in one second. It was again shown that Jackie's race speed is 5.3 meter per second and all the other three namely Jeremy's speed is 3.9 meter per second, Mike's speed is 4.1 meter per second and finally Niki's speed is 3.8 meter per second.
  • So, by comparing with others Jackie is the fastest runner in that race.
