How many molecules of oxygen are in 3.0 moles of oxygen?

Chemistry
2 answers:
Daniel [21]3 years ago
7 0

Answer:

18.066× 10²³ molecules

Explanation:

Given data:

Number of moles of oxygen = 3.0 mol

Number of molecules = ?

Solution:

The given problem will solve by using Avogadro number.

It is the number of atoms , ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance.  The number 6.022 × 10²³ is called Avogadro number.

1 mole = 6.022 × 10²³ molecules

3 mol  × 6.022 × 10²³ molecules  / 1 mol

18.066× 10²³ molecules

How could you use
ExtremeBDS [4]

Answer:

The procedure with the  simple calorimeter to  compare the energy released  by different fuels is described below in detail.

Explanation:

If the response delivers heat (rxn < 0), then heat is consumed by the calorimeter (calorimeter > 0), and its temperature improves. Conversely, if the response consumes heat (rxn > 0), suddenly heat is carried from the calorimeter to the arrangement (calorimeter < 0), and the temperature of the calorimeter drops.

Calculate the energy for vacancy formation in silver, given that the equilibrium number of vacancies at 800˚C (1073 K) is 3.6 ×
krek1111 [17]

Answer : The energy for vacancy formation in silver is, 1.762\times 10^{-19}J

Explanation :

Formula used :

N_v=N\times e^{(\frac{-E}{K\times T})}

or,

N=\frac{N_A\times \rho}{M}

So,

N_v=[\frac{N_A\times \rho}{M}]\times e^{(\frac{-E}{K\times T})}

where,

N_v = equilibrium number of vacancies = 3.6\times 10^{23}m^{-3}=3.6\times 10^{20}L^{-1}

E = energy = ?

M = atomic weight = 107.9 g/mole

N_A = Avogadro's number = 6.022\times 10^{23}mol^{-1}

\rho = density = 9.5g/cm^3=9.5g/ml=9500g/L

T = temperature = 800^oC=273+800=1073K

K = Boltzmann constant = 1.38\times 10^{-23}J/K

Now put all the given values in the above formula, we get:

3.6\times 10^{20}L^{-1}=[\frac{(6.022\times 10^{23}mol^{-1})\times 9500g/L}{107.9g/mol}]\times e^{[\frac{-E}{(1.38\times 10^{-23}J/K)\times 1073K}]}

E=1.762\times 10^{-19}J

Therefore, the energy for vacancy formation in silver is, 1.762\times 10^{-19}J

The planet Mercury takes 176 days to do one spin around its pole. Compared to the Earth,
Tanya [424]

Answer:

The sun would appear to move more slowly across Mercury's sky.

Explanation:

This is because, the time it takes to do one spin or revolution on Mercury is 176 days (which is its period), whereas, the time it takes to do one spin or revolution on the Earth is 1 day.

Since the angular speed ω = 2π/T where T = period

So on  Mercury, T' = 176days = 176 days × 24 hr/day × 60 min/hr × 60 s/min = ‭15,206,400‬ s

So, ω' = 2π/T'

= 2π/15,206,400‬ s

= 4.132 × 10⁻⁷ rad/s

So on  Earth, T" = 1 day = 1 day × 24 hr/day × 60 min/hr × 60 s/min = ‭‭86,400‬ s

So, ω" = 2π/T"

= 2π/86,400‬ s

= 7.272 × 10⁻⁵ rad/s

Since ω' = 4.132 × 10⁻⁷ rad/s << ω" = 7.272 × 10⁻⁵ rad/s, <u>the sun would appear to move more slowly across Mercury's sky.</u>
