# 3-Solve the following problem. Round the partial pressure of SF6 to one significant figure.
Subtract 2 from the only significant figure to find the value of C in the combination. (difficulty
level- very hard) A student analyzes a gas mixture of sulfur hexafluoride (SF6) and selenium
hexafluoride (SeF6) and finds that the density of the sample is 6.90 g/L at a temperature of 23°C
and a pressure of 0.942 atm. Calculate the partial pressure of sulfur hexafluoride.
