The answer is 18.

This is obtained by multiplying the three oxygen atoms in NO₃, that are inside the parenthesis by the number two outside the parenthesis. The number 2 is there because it comes from associating with Fe ²⁺ .
 3×2=6 oxygen atoms present in the formula.

Then multiplied by the 3 that's in front of the formula (that indicates how many molecules).
6 x 3= 18

A 10-liter container has 2 moles of oxygen at a pressure of 92 kpa. The effective speed (rms) of the oxygen molecules in the gas
bezimeni [28]

The effective speed (rms) of the oxygen gas is 293.68 m/s.

<h3></h3><h3>What is Root-mean-square velocity?</h3>

Root mean square velocity is the square root of the mean of squares of the velocity of individual gas molecules

v_{rms}=\sqrt[]{\frac{3RT}{M} }

<em>where </em>R = universal gas constant

M = molar mass of the gas in kg/mol

T = temperature in Kelvin

According to the ideal gas law,

PV = nRT

RT = \frac{PV}{n}

Substitute in the rms velocity formula,

v_{rms} = \sqrt[]{\frac{3PV}{nM} }

P = 92 kPa, V = 10 L, n = 2 moles and M = 32 x 10⁻³ kg/mol

v_{rms} = \sqrt[]{\frac{3\times92\times10}{2\times32\times10^-^3} }

=293.68 m/s

Thus, the effective speed (rms) of O₂ gas is 293.68 m/s.

If the volume of the original sample in Part A ( P1 = 242 torr , V1 = 27.0 L ) changes to 80.0 L , without a change in the tempe
Brrunno [24]

The new pressure is 81.675 torr

Since temperature and moles are held constant, we use Boyle's Law:

A gas law known as Boyle's law asserts that a gas's pressure is inversely proportional to its volume when it is held at a fixed temperature and of a given mass.

To put it another way, as long as the temperature and volume of the gas remain constant, the pressure and volume of the gas are inversely proportional to one another.

The Anglo-Irish chemist Robert Boyle proposed Boyle's law in the year 1662.

P1V1=P2V2. Simply plug in your values. The units can remain in torr. Converting to atmospheres is not needed.

(242 torr)(27.0 L)=P2(80.0 L)

P2=[(242)(27)]/80 = 81.675 torr

Hence The new pressure is 81.675 torr
