Answer:
[tex]89.17\text{ kPa}[/tex]Explanation:
Here, we want to get the required pressure in kPa
We start by writing the ideal gas equation
We have that as:
[tex]PV\text{ = nRT}[/tex]where P is the pressure we want to calculate
V is the volume which is 4.2 L
n is the number of moles which is 0.15
T is the temperature which we will convert to Kelvin by adding 273K:
We have that as 273 + 23 = 300K
R is the molar gas constant which is 0.0821 L.atm/mol.K
Substituting the values, we have it that:
[tex]P\text{ = }\frac{nRT}{V}\text{ = }\frac{0.15\text{ }\times0.0821\times300}{4.2}\text{ = 0.88 atm}[/tex]Finally, we convert the pressure in atm to pressure in kPa
To do this, we multiply the atm value by 101.325
We have that as:
[tex]0.88\text{ }\times\text{ 101.325 = 89.17 kPa}[/tex]
