Find the volume of 6.45 moles of gas present at a temperature of 27.0oC and a pressure of 675 torr.
maw [93]

<u>Answer:</u> The volume of the gas is 178.76 L

<u>Explanation:</u>

The ideal gas equation is given as:

.......(1)

where

P = pressure of the gas = 675 torr

V = volume of gas = ?

n = number of moles of gas = 6.45 moles

R = Gas constant = 62.36 L.torr/mol.K

T = temperature of the gas = 27^oC=[27+273]K=300K

Putting values in equation 1, we get:

675torr\times V=6.45mol\times 62.36L.torr/mol.K\times 300K\\\\V=\frac{6.45\times 62.36\times 300}{675}=178.76 L

Hence, the volume of the gas is 178.76 L

If a 750 mL of a gas at a pressure of 100.7 kPa has a decrease of pressure to 99.8 kPa, what is the new volume? Show work
SVEN [57.7K]

Explanation:

P1V1 = P2V2

(100.7 kPa)(0.75 L) = (99.8 kPa)V2

V2 = (100.7 kPa)(0.75 L)/(99.8 kPa)

= 0.757 L
