Don’t currently have a calculator with me but just use Avogadros constant (A) 6.02x10^24, in the equation n=N/A. Lower case n being the number of mol and upper case being the number of molecules (given).

At what temperature does 0.019135 moles of Ne in a 878.3 mL container exert a pressure of 0.946 atm?
Reika [66]
<h3>Answer:</h3>

Temperature is 529.164 K

<h3>Explanation:</h3>

We are given

Number of moles of Ne (n) =  0.019135 moles

Volume (V) = 878.3 mL

Pressure (P) = 0.946 atm

We are required to calculate the temperature;

We can do this using the ideal gas law equation which is;

PV = nRT, where P is the pressure, n is the number of moles, V is the volume, R is the ideal gas constant (0.082057 Latm/mol/K) and T is the temperature.

From the equation;

T=\frac{PV}{nR}

T = \frac{(0.946)(0.8783)}{(0.082057)(0.019135)}

T=529.164 K

Therefore, the temperature will be 529.164 K.
