Answer:

<em> Pressure exerted by the gas is 574.85 torr</em>

Explanation:

Atmospheric pressure = 751 torr

but 1 torr = 1 mmHg

therefore,

atmospheric pressure = 751 mmHg

1 mmHg = 133.3 Pa

therefore,

atmospheric pressure = 751 x 133.3 = 100108.3 Pa

distance labeled (tube section with mercury) = 176 mm

the pressure within the tube will be

P_{tube} = ρgh

where ρ is the density of mercury = 13600 kg/m^3

h is the labeled distance = 176 mm = 0.176 m

g is acceleration due to gravity = 9.81 m/s^2

P_{tube}  = 13600 x 9.81 x 0.176 = 23481.216 Pa

The general equation for the pressure in the manometer will be

P_{atm} = P_{tube} + P_{gas}

where P_{atm}  is the atmospheric pressure

P_{tube}  is the pressure within the tube with mercury

P_{gas} is the pressure of the gas

substituting, we have

100108.3 = 23481.216 + P_{gas}

P_{gas} = 100108.3 - 23481.216 = <em>76627.1 Pa</em>

This pressure can be stated in mmHg as

76627.1 /133.3 =<em> 574.85 mmHg </em>

and also equal to<em> 574.85 torr</em>

How many moles are in 2.1 x 10^{24} molecules SiO4
lozanna [386]

Answer: 3.5 moles

Explanation:

Based on Avogadro's law:

1 mole of any substance has 6.02 x 10^23 molecules

So, 1 mole of SiO4 = 6.02 x 10^23 molecules

Zmoles of SiO4 = 2.1 x 10^{24} molecules

To get the value of Z, cross multiply:

(2.1 x 10^{24} molecules x 1mole) = (6.02 x 10^23 molecules x Z moles)

2.1 x 10^{24} molecules = (6.02 x 10^23 x Z)

Z = (2.1 x 10^{24}) ➗ (6.02 x 10^23)

Z = 3.5 moles

Thus, there are 3.5 moles of SiO4.
