Oxygen gas is collected at a pressure of 123 kPa in a container which has a volume of 10.0L. What temperature must be maintained
Morgarella [4.7K]
Given:

P = 123 kPa
V = 10.0 L
n = 0.500 moles
T = ?

Assume that the gas ideally, thus, we can use the ideal gas equation:

PV = nRT

where R = 0.0821 L atm/mol K

123 kPa * 1 atm/101.325 kPa * 10.0 L = 0.500 moles * 0.0821 Latm/molK * T

solve for T 

T = 295.72 K<span />

When performing dimensional analysis, we usually use conversion factors. What is a conversion factor?
lora16 [44]

Answer:

A conversion factor is a variable that transforms the dimension of one variable into the terms of another variable.

Explanation:

Let be x and y two variables with diferent dimensions (units), r is a conversion if transforms the dimension of one variable into the terms of the other variable. That is:

y = r\cdot x (1)

Where:

x - Input, [input unit]

y - Output, [output unit]

r - Conversion factor, [output unit] per [input unit]
