A gas sample has a volume of 4250 mL at 15 degree Celsius and 745 mmHg. What is the final temperature, in degree Celsius, after the sample is transferred to a different container with a volume of 2.50 L and a pressure of 1.20 atm if the amount of gas does not change?

Explanation:

Given;

volume=4250 mL at 15 degree C and 745 mm Hg

Formula used:

PV=nRt

Solution:

After transfer of ags moles of gas will remain same

in the given question, the partial pressure is calculated by using the ideal gas equation, that is, pv = nrt

here, p is pressure, v is volume = 25 l, n is number of moles = 0.0104 moles, r is gas constant = -0.0821 l.atm / mol.k

t is temperature = 273 k

p = nrt / v

p = (0.0104 mol × 0.0821 l.atm / mol.k × 273 k) / 25 l

= 0.0093 atm

the answers would be

the first one and the second one
