Answer 2

Given - Volume : 8.4 liter

Temperature : 24° C

Weight : 7 gram

Find - Pressure of gas

Solution - Taking the value of gas constant 0.082 L atm/mol K.

Using ideal gas equation to find pressure of gas under given conditions. The relation is P*V = n*R*T. Here, p is pressure, v is volume, n is number of moles, R is gas constant and T is temperature.

Firstly finding number of moles by the formula weight/molecular weight.

Number of moles = 7/28

Number of moles = 1/4

Number of moles = 0.25

Temperature of 24° C in Kelvin = 297 Kelvin

Keeping the values in ideal gas equation -

P = nRT/V

P = 0.25*0.082*297/8.4

P = 0.72 atm

Hence, pressure of gas is 0.72 atm
