1. (a) A column of water in a buret is 336 mm Hg high. How high would that column be if it were mercury instead of water? In order for the pressures to be equal, density and height of a column are inversely proportional, therefore the following relationship applies: (denHg) (hHg) = (denH20)(hH₂0) Note: the density of mercury is 13.6 g/mL and the density of water is 1.00 g/mL. Show full calculation of the height in mercury (remember to use proper significant figures.)

Question
(a) (c) A column of water in a buret is 336 mm Hg high. How high would that column be if it were mercury instead of water? (d) In order for the pressures to be equal, density and height of a column are inversely proportional, therefore the following relationship applies: (denHg)(hHg) = (denH20)(hH20) Note: the density of mercury is 13.6 g/mL and the density of water is 1.00 g/mL. An electrolysis experiment was run for 15 minutes and 45 seconds at an average current of 189 milliamps (mA). The mass lost by the copper anode was 0.0589 grams. (b) Calculate the number of coulombs transferred. (Remember: coulomb = amps x sec) Show full calculation of the height in mercury (remember to use proper significant figures.) Calculate the moles of copper lost from the anode. Based on the moles of copper lost determined in 1c, calculate the moles of electrons transferred. Remember, the reaction at the copper anode is: Cu(s)---> Cu¹² (aq) + 2 e
