then b is 4

2a=3b since a=6

2x6=3b

12=3b

b=12/3

b=4

Answer:

b=4

Explanation:

2a=3b

2a=2*6

2*6=12

2a=12

12=3b

12/3=4

b=4

Answer:

See Explanation

Explanation:

Given

2500 meters

200 grams

Required

How do they compare?

You can't compare these two measurements in terms or size, units and measurements because they measure two different quantities

2500 meters measures length or distance

while

200 grams measures mass of objects

A gaseous mixture at 265K and 1.0 atm contains 25 O2 60 N2 and 15 CO2 mole basis The velocities of the components are 0.084 cm s

Free_Kalibri [48]

Answer:

The molar average velocity is 0.0588 cm/s

The N₂ diffusion velocity relative to the mole average velocity is -0.1428 cm/s

The molar diffusional flux of N₂ is -3.9x10⁻³

Explanation:

Given data:

T = temperature = 265 K

O₂ = 25%

N₂ = 60%

CO₂ = 15%

vO₂ = -0.084 cm/s

vN₂ = 0.12 cm/s

vCO₂ = 0.052 cm/s

The molar average velocity is equal:

$v_{av} =(0.25*(-0.084))+(0.6*0.12)+(0.15*0.052)=0.0588cm/s$

The N₂ diffusion velocity relative to the molar average velocity is:

$v_{i} -v_{av} =-0.084-0.0588=-0.1428cm/s$

The molar diffusional flux of N₂ is:

$N_{N_{2} } =\frac{P}{RT} y_{A} (v_{i} -v_{av} )=-3.9x10^{-3}$
