Estimated 3σ error is 1.2 cm3/mol; error is 17, 23, and 34 percent at 30, 40, and 50 °C, respectively.
Estimated error is 24, 16, and 11 percent at 30, 40, and 50 °C, respectively.
Estimated error is nominally 43 percent at 30, 40, and 50 °C.
Quadrature of errors contributed by Henry’s law, gas constant, and ignoring the correction to the law of ideal solutions.
Computed by the square root of the sum of the squares of the individual terms.
