5. What is the amount of moles of nitrous oxide gas (N2O) used to sedate Mr. Muthbefore his wisdom teeth are pulled? The pressure is 2.5 atm, a temperature of 25.0°C,and volume of 1.67L?

Respuesta :

Answer:

0.171moles

Explanations

According to the ideal gas equation;

[tex]PV=nRT[/tex]

where:

• P is the, pressure ,in atm

,

• V is the ,volume ,in litres

,

• n is the ,number of moles ,of gas

,

• R is the, boltzmann constant

,

• T is the, temperature ,in Kelvin

Given the following parameters

P = 2.5atm

V = 1.67L

T = 25.0°C = 25 + 273 = 298K

R = 0.08205Latm/molK

Substitute the given parameters into the formula

[tex]\begin{gathered} n=\frac{PV}{RT} \\ n=\frac{2.5\times1.67}{0.08205\times298} \\ n=\frac{4.175}{24.4509} \\ n=0.171mole \end{gathered}[/tex]

Hence the amount of moles of nitrous oxide gas used is 0.171moles
