Lab # 28: Calculating the Value of the Ideal Gas Constant “R”
... Disposable plastic lighters are filled with lighter fluid, mostly butane (C4H10), which liquefies under pressure. In this lab, you will use the ideal gas law to calculate the value of the ideal gas constant “R”. We will collect a sample of gas from a lighter by water displacement. See Figure 1 for t ...
