How many miles of barium hydroxide are in 2400 grams of ba(oh)2

C would be the correct one

2400 g Ba(OH)_2 = 14.01 Ba(OH)_2

M_r = 137.33 + 2(16.00 + 1.008) = 137.33 + 2×17.008 = 137.33 + 34.016 = 171.346

Moles of Ba(OH)_2= 2400 g Ba(OH)_2 × [1 mol  Ba(OH)_2/171.346 g Ba(OH)_2] = 14.01 mol Ba(OH)_2

pure water does not conduct electricity very well. however, when certain substances are dissolved in water, the solution does conduct electricity. you can make a simple device that shows how well a solution conducts electricity. this device uses a flashlight bulb to indicate how well the solution conducts electricity. the better the solution conducts electricity, the brighter the bulb will glow.
