Atomic mass iron ( Fe ) = 55.84 a.m.u

55.84 g ------------ 6.02x10²³ atoms
24.0 g ------------- ??

24.0 x ( 6.02x10²³) / 55.84

=> 2.58x10²³ atoms

A 1. 00 ml sample of an unknown gas effuses in 11. 1 min. an equal volume of h2 in the same apparatus under the same conditions
Damm [24]

A 1. 00 ml sample of an unknown gas effuses in 11. 1 min. an equal volume of h2 in the same apparatus under the same conditions effuses in 2. 42 minutes then the molar mass of the unknown gas is 41.9.

Molar mass of H2 = 2

Molar mass of unknown gas = ?

rate 1 = 11.1

rate 2 = 2.42

<h3>What is graham law? </h3>

Graham's law states that the rate of diffusion or effusion of a given gas is inversely proportional to the square root of its molar mass.

By apply graham law

Rate1/rate2 = sqrt(MW2/MW1)

[\frac{rate1}{rate2} ]^{2} = \frac{MW2}{2} \\\\\\mw= 2[\frac{11.1}{2.42} ]^{2} \\\\= 20.97 X 2 \\\\= 41.9

Thus, we found that the molar mass of the unknown gas is 41.9.

Question 5 (1 point)<br> How many moles of oxygen gas is needed to produce 36 grams of water?
Alecsey [184]

Answer:

1 Oxygen atom has a mass of 16 grams, thus diatomic oxygen weights twice as much- 32 grams. Hence 32 grams is needed.

In which sample is the average kinetic energy of the particles the greatest?
tangare [24]
Temperature is a measurement of average kinetic energy of the particles in a sample which means that the sample with the highest temperature has the highest average kinetic energy of the particles.

That being said the answer would be 4) 10 mL of H2O (l) at 35 degrees Celsius since that sample has the largest temperature.

I hope this helps.  Let me know if anything is unclear.

What will happen if a peeled banana is put on a hotplate? Will it undergo a physical or a chemical change?
FinnZ [79.3K]
I would say physical, because a physical change is affecting the form of a chemical substance, but not it's chemical makeup.
