Question

For each of your 3 trials, enter the pressure in mmHg exerted by the column of liquid in your beret Remember that Hg is 13.6 times as dense as water You should use 3 significant figures in your result. Data Entry - no scoring for each of your NCount trials, enter the distance in millimeters between the liquid level in the beaker and the meniscus in the beret at the end of the hydrolysis time Remember to keep the same sequence for aH your tonal data that you establish when you enter the values here. Report the distance to the nearest mm. e.g. 183 mm.

Explanation / Answer

we know that standard atmoshpheric pressure = 760 mm of Hg,

now we can calculate the pressure exerted by liquid in buret as,

trail 1= height 760-114 mm = 646 mm of Hg,

trail 2= 760-156= 604 mm of Hg,

3) trail 3 = 760-167 = 593 mm of Hg
