How many moles of oxygen atoms are in 132.2 g of MgSO4?

zzz [600]

4.4moles of oxygen atoms

Explanation:

Given parameters:

Mass of MgSO₄ = 132.2g

Unknown:

Number of moles of oxygen atoms = ?

Solution:

The number of moles is the quantity of substance that contains the avogadro's number of particles.

To solve for this;

Number of moles = $\frac{mass}{molar mass}$

Molar mass of MgSO₄ = 24 + 32 + 4(16) = 120g/mole

Number of moles = $\frac{132.2}{120}$ = 1.1 moles

1 moles of MgSO₄ we have 4 moles of oxygen atoms

1.1 moles of MgSO₄ contains 4 x 1.1 moles = 4.4moles of oxygen atoms

Molecular bromine is 24 percent dissociated at 1600 k and 1.00 bar in the equilibrium br2 (

dlinn [17]

Br2 == 2Br

24% dissociated => n total moles, 0.24 mol*n of Br, and 0.76*n mol of Br2

=> partial pressure of Br, P Br = 0.24 bar, and
partical pressure of Br2, P Br2 = 0.76 bar

kp = (P Br)^2 / P Br2 = (0.24)^2 / 0.76 = 0.0758

Which object(s) formed last in our solar system?

AnnyKZ [126]

Long year ago In space, gravity attracts dust and gas together which created the young solar system. It pulled low-density cloud together to produce initially the solar nebula. These clouds are made of interstellar gas and dust.

The sun formed first from these nebula and dust.

Planetesimals is just a process indicates the formation of Earth and the other planets from concentrations of dust and diffused matter in the solar system.

Inner planets are the planets located closure to the sun in comparison to outer planets. These inner planets are mercury, venus, earth and mars. Thus, 4.5 billion year ago Inner planets formed at last.

A 20.6-L sample of "pure" air is collected in Greenland at a temperature of 220.0°C and a pressure of 1.01 atm and is forced int

KATRIN_1 [288]

Answer :

(a) The pressure inside the bottle just after it filled is 19.8 atm.

(b) The pressure inside the bottle as it opened in the 21.0°C is 11.8 atm.

Explanation :

Boyle's Law : It is defined as the pressure of the gas is inversely proportional to the volume of the gas at constant temperature and number of moles.

$P\propto \frac{1}{V}$

or,

$P_1V_1=P_2V_2$

where,

$P_1$ = initial pressure of gas = 1.01 atm

$P_2$ = final pressure of gas = ?

$V_1$ = initial volume of gas = 20.6 L

$V_2$ = final volume of gas = 1.05 L

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

$1.01atm\times 20.6L=P_2\times 1.05L$

$P_2=19.8atm$

Therefore, the pressure inside the bottle just after it filled is 19.8 atm.

Gay-Lussac's Law : It is defined as the pressure of the gas is directly proportional to the temperature of the gas at constant volume and number of moles.

$P\propto T$
