8. If 0.795 moles of ammonia gas occupies 42.5 L at 670 torr, what is the Celsius temperature?
maksim [4K]

<u>Answer:</u> The temperature in degree Celsius is 301.31°C

<u>Explanation:</u>

To calculate the temperature, we use the equation given by ideal gas, which is:

PV=nRT

P = pressure of the gas = 670 torr = 0.882 atm   (Conversion factor: 1 atm = 760 torr)

V = volume of gas = 42.5 L

n = number of moles of gas = 0.795 mol

R = Gas constant = 0.0821\text{ L atm }mol^{-1}K^{-1}

T = temperature of gas

Putting values in above equation, we get:

0.882atm\times 42.5L=0.795mol\times 0.0821\text{ L atm }mol^{-1}K^{-1}\times T\\\\T=574.31K

Converting the temperature from kelvins to degree Celsius, by using the conversion factor:

T(K)=T(^oC)+273

574.31=T(^oC)+273\\T(^oC)=301.31^oC

Hence, the temperature in degree Celsius is 301.31°C
