Question

At what temperature will 0.0705 mol of Cl2 exert a pressure of 900. torr at a volume of 0.750L?

Answer 1

It will exert the pressure at a temperature of 153.44 K

Step-by-step explanation:

To answer this question, we shall be using the ideal gas equation;

PV = nRT

Since we are calculating the temperature, it can be made the subject of the formula.

Thus, this can be T = PV/nR

where P is the pressure = 900 torr

V is the volume = 0.75 L

n is the number of moles = 0.0705 mol

R is the molar gas constant = 62.4 L.Torr.
`k^(-1)`.
`mol^(-1)`

Plugging these values into the equation, we have;

T = (900 × 0.75)/(0.0705 × 62.4)

T = 153.44 K
