This chart show the amount of radioactivity measured from three unknown isotopes.
Which statement describes each of the isotopes?
Isotope A was measured at day 24, Isotope B was measured at day 6, and Isotope C was measured at day 10.
Isotope A was measured at day 18, Isotope B was measured at day 4, and Isotope C was measured at day 5.
Isotope A was measured at day 24, Isotope B was measured at day 8, and Isotope C was measured at day 20.
Isotope A was measured at day 30, Isotope B was measured at day 6, and Isotope C was measured at day 10.

Since the gas in your graduated cylinder is a mixture of butane and water vapor, you must determine the partial pressure of the butane, pbutane, alone. to do this, consult a reference and record the partial pressure of the water vapor, pwater, at the temperature you recorded. use the following formula to compute the partial pressure of the butane. pbutane = atmosphere - pwater use the following combined gas law formula and compute the volume that the butane sample will occupy at stp. (hint: convert both temperatures to kelvin.) pbutane x voriginal = pstandard x vfinal troom tstandard use the following ratio and proportion formula to determine the mass of butane needed to occupy a volume of 22.4 l at stp. grams of butane you used “x” grams of butane ml of butane corrected to stp = 22,400 ml compute the theoretical molar mass of butane based on its formula and the atomic masses on the periodic table. compare your experimental results from #3 to the theoretical value of #4, computing a percent error of your findings using this formula: % error = measured value - accepted value x 100 accepted value use the following ratio and proportion formula to determine the mass of butane needed to occupy a volume of 22.4 l at stp. need asap
